Anxiety and Codependency: Why Being Alone Feels Unbearable
📖 16 min read🧠 MyAnxietyTest📅 June 2026
A free evening should be a relief. Instead, within minutes of the apartment going quiet, there is a restless, almost physical discomfort, and the search begins immediately: who can I call, what plans can I make, is there anyone available right now. A relationship that, if you are honest with yourself, has not been working for a long time still feels like it would be worse to lose than to keep enduring. The idea of being properly, deliberately alone, not for an hour but for an evening, a weekend, longer, produces a kind of dread that feels entirely disproportionate to what being alone actually involves. If any of this is familiar, it is worth taking seriously that this is not simply a preference for company. It is very often anxiety, operating through a specific mechanism that makes solitude itself feel unsafe.
Codependency gets discussed often as a relational pattern, something that happens between two people, one who needs too much and one who gives too much. That framing is not wrong, but it skips past the part that actually drives the behaviour: what is happening inside the person who cannot seem to be alone. This article looks at that internal experience directly, in detail, because understanding why being alone feels unbearable, rather than simply being told to "work on yourself" or "love yourself first," is what actually makes it possible to build a different relationship with solitude.

Map the specific avoidance behind your discomfort with being alone
The Anxiety Avoidance Profile identifies the specific situations and fears driving avoidance patterns, including the difficulty tolerating solitude that often sits underneath codependent relationship patterns.
Codependency frequently functions as a strategy for avoiding the anxiety produced by being alone, specifically the discomfort of facing one's own unstructured thoughts and an identity that has never been clearly defined independently of another person. The presence of someone, almost regardless of how well the relationship is actually going, provides relief from that discomfort, which can make staying in something unsatisfying feel safer than the alternative of confronting solitude directly.
The mechanism
Why the presence of another person, more than the quality of the relationship, becomes the priority
1
Solitude removes the external structure another person provides
A partner, friend, or even a casual acquaintance's presence provides built in structure and distraction: conversation, shared activity, attention directed outward. When that presence is removed, attention has nowhere obvious to go except inward, toward whatever thoughts and feelings have been quietly waiting underneath the noise of daily life and company.
2
What surfaces in that quiet is frequently anxious or uncomfortable
For someone with a significant anxious baseline, alone time often means encountering unresolved worry, self criticism, or a sense of identity that feels unstable or undefined without someone else's presence to reflect off of. This is genuinely uncomfortable, not simply boring, which is an important distinction from ordinary preferences about socialising.
3
Another person's presence resolves the discomfort immediately and reliably
Being with someone, almost any reasonably tolerable someone, reliably removes that discomfort by providing the external focus that solitude lacks. This relief is powerful and immediate, which makes seeking company an extremely effective short term solution to an uncomfortable internal state.
4
The relationship's actual quality becomes secondary to its existence
Because the underlying need being met is the relief from being alone, not necessarily anything specific to this particular relationship, the actual compatibility, health, or satisfaction of the relationship can matter less than its simple presence in a person's life, which is precisely how unsatisfying relationships persist far longer than they otherwise would.
5
The capacity to tolerate being alone never gets the chance to develop
Because solitude is consistently avoided rather than experienced and gradually tolerated, the underlying discomfort it produces never has the opportunity to reduce naturally, which means the avoidance, and the relationships built around preventing it, tend to persist indefinitely without intervention.
"The problem has rarely been that you love too much. It is that being without someone has felt like being without a structure for your own mind."
Where this shows up
The specific situations and decisions where anxiety driven codependency tends to be most visible
Situation
How the pattern typically appears
Staying in unsatisfying relationships
Remaining in a relationship that is clearly not meeting your needs, sometimes for years, because ending it would mean confronting being alone, which feels like the worse of two outcomes.
Rushing into new relationships
Moving quickly from one relationship to another with little or no time alone in between, sometimes choosing partners primarily for their immediate availability rather than genuine compatibility.
Difficulty making independent plans
Structuring free time almost entirely around other people's availability, with genuine reluctance or anxiety about spending an evening or weekend with no plans involving someone else.
Over-functioning to keep someone close
Taking on disproportionate emotional or practical labour in a relationship, not necessarily out of generosity, but to make oneself indispensable enough that the other person stays.
Friendship patterns
Maintaining contact with friendships that have become one sided or unsatisfying, for similar reasons: the presence of the connection matters more than its current quality.

The accumulated toll of consistently avoiding solitude rather than learning to tolerate it
What chronic avoidance of being alone costs across years
⚖️
Relationship choices driven by availability, not compatibility
When the primary criterion for a relationship is simply that it exists, the actual fit between two people becomes secondary, often producing a string of relationships that are adequate at best rather than genuinely fulfilling.
🪞
An identity that never gets the chance to solidify independently
Without time spent genuinely alone with one's own thoughts, preferences, and interests, a stable sense of identity that exists independently of any particular relationship can remain underdeveloped well into adulthood.
🔁
A repeating cycle across multiple relationships
Because the underlying driver is the anxiety of being alone rather than anything specific to one relationship, the same pattern, staying too long, rushing into the next one, frequently repeats across a person's entire relationship history.
😔
Genuine loneliness despite rarely being physically alone
Paradoxically, relationships maintained primarily to avoid solitude often fail to provide genuine emotional connection, leaving a person surrounded by company while still feeling a deep, persistent loneliness underneath it.
What actually builds the capacity to be alone
Specific, gradual approaches that build genuine tolerance rather than forcing an abrupt, overwhelming change
⏱️
Practise solitude in small, deliberately bounded amounts
Rather than attempting a full unstructured weekend alone immediately, start with short, defined periods, thirty minutes, an hour, with a specific low pressure activity. Building tolerance gradually is significantly more sustainable than attempting to tolerate a large amount of alone time all at once.
📝
Notice and name what actually surfaces during alone time
Rather than immediately reaching for distraction or company the moment discomfort arises, briefly noting what thought or feeling has surfaced, a worry, a memory, a sense of restlessness, builds familiarity with what solitude actually contains, which tends to be less threatening once it is specifically named.
🎨
Develop interests and activities that exist independently of other people
Cultivating something genuinely engaging that does not require another person's presence, a hobby, a creative pursuit, physical activity, gives alone time a structure and purpose of its own, rather than leaving it as empty space that anxiety rushes to fill.
🔍
Examine relationship decisions for what is actually driving them
Before staying in or entering a relationship, asking directly whether the decision is based on genuine compatibility and care, or primarily on avoiding the discomfort of being without it, can surface a pattern that is otherwise difficult to see from inside a specific relationship.
🧠
Address the underlying anxiety with professional support
The approaches above build practical tolerance gradually. CBT with a licensed therapist works directly on the anxious thoughts that surface in solitude and on developing a sense of identity and self worth that does not depend entirely on another person's presence.
What changes once solitude itself stops feeling like the enemy
CBT does not ask you to enjoy being alone immediately. It builds the actual capacity to tolerate it, one deliberate step at a time.

"
I stayed in a relationship I knew wasn't right for almost two years because the thought of being single felt worse than being unhappy. My therapist helped me see that pattern clearly for the first time, and gave me actual steps to build tolerance for being alone instead of just telling me to "love myself."

A free Saturday used to send me into a panic of texting everyone I knew. We started with just twenty minutes alone with no phone, building up slowly. Six months later I genuinely look forward to a quiet weekend, which is something I would never have believed before.

What being genuinely okay alone would feel like
The shift this work is actually aiming toward
It would not mean preferring solitude to connection, or losing interest in relationships entirely. Most people who build this capacity still deeply value their relationships, often more so, because those relationships start being chosen for their actual quality rather than for their function as an escape from being alone. What changes is the floor underneath everything: solitude stops being something to be managed or avoided and becomes simply one of several available states, sometimes restful, sometimes quiet, occasionally still a little uncomfortable, but never again unbearable in the way it once was. The relationships that remain after this shift tend to be the ones that were genuinely working all along, no longer obscured by the urgent need for company at any cost.
If a quiet evening has ever sent you searching for anyone to call, or if a relationship you knew was not right has felt safer than the alternative of no relationship at all, the problem has never been an excess of love. It has been a fear of facing yourself without anyone else in the room.
Being unable to tolerate solitude is not a flaw in your capacity to love. It is anxiety, and it has a clear path toward something better.
A licensed CBT therapist works with you to build genuine, gradual tolerance for being alone, helps identify what specifically surfaces in that quiet that has felt so threatening, and supports the development of an identity and sense of worth that holds steady whether or not someone else is present.

Frequently asked questions
Anxiety and codependency
For many people, yes. Codependency frequently functions as a strategy for avoiding the anxiety produced by being alone, particularly the discomfort of being alone with one's own unstructured thoughts and an identity not clearly defined independently of a relationship. According to the American Psychological Association, avoidance behaviours like this are a well documented feature of anxiety.
For someone with significant anxiety around being alone, solitude removes the distraction another person's presence provides, leaving more space for anxious thoughts to surface without anything external to manage them, producing distress disproportionate to what being alone would ordinarily cause.
When the underlying driver is anxiety about being alone rather than attachment to a specific partner, the relationship's actual quality can become secondary to its simple existence. Ending it would mean confronting the alone time it has been helping to avoid, which can feel worse than staying.
No. Genuine commitment involves choosing a relationship for its specific qualities while maintaining independent identity and tolerating time apart. Codependency driven by anxiety about being alone often persists with little regard for relationship quality, since the need being met is presence, not necessarily this specific relationship.
