One of the most distressing aspects of severe anxiety is the feeling that you are losing your mind. Not in a casual sense. In the literal sense: that your thoughts are out of control, that you are detached from reality, that you cannot trust your own perceptions, that something is genuinely wrong with you beyond anxiety.
This feeling is extremely common in anxiety and it has specific, well-understood causes. You are not going crazy. What you are experiencing has a name, a mechanism, and a treatment. That distinction matters enormously when you are in the middle of it.
Derealisation, the feeling that the world is unreal or dreamlike, and depersonalisation, the feeling of being detached from yourself, are among the most alarming anxiety symptoms. They tend to first appear during intense anxiety or panic episodes and can be so frightening that they immediately escalate the anxiety further.
Both are anxiety symptoms, not signs of psychosis or schizophrenia. They occur because the brain, when overwhelmed by threat signals, activates a kind of emotional dampening mechanism. The dissociative quality, the dreamlike or detached feeling, is the nervous system pulling back from an experience it finds overwhelming.
The crucial thing to understand is that fighting these feelings intensifies them. The more you focus on whether things feel real, check whether you feel like yourself, or try to force the unreal feeling away, the stronger the dissociation tends to become. The counterintuitive but effective approach is to allow the feeling to be present without engaging with it as a threat.
During high anxiety states, the prefrontal cortex, which normally filters, organises, and regulates thought content, becomes less effective at its regulatory role. The result is that thoughts arrive faster, seem less under your control, and include content that feels alien or frightening. Intrusive thoughts, unwanted thoughts that seem to arrive from nowhere and contradict your values or wishes, are particularly common.
The anxious response to intrusive thoughts is typically to try to suppress them, reassure yourself that you do not mean them, or monitor yourself for signs that they indicate something serious about you. All three responses increase the frequency and intensity of the intrusive thoughts. The article on intrusive thoughts and anxiety covers why this happens and what actually works instead.
The fear of going mad is itself one of the recognised anxiety symptoms, particularly in panic disorder. It is distressing and alarming, but it is the anxiety catastrophising about the anxiety symptoms rather than evidence of actual psychiatric deterioration.
People who are genuinely losing touch with reality do not typically have the insight to worry about it in the way that anxious people do. The very fact that you are worried about your grip on reality, that you can identify the experience as strange and frightening, is evidence that your reality-testing is intact.
For derealisation and depersonalisation: grounding techniques that bring attention to concrete physical sensation are the most effective immediate intervention. Five things you can see, four you can touch and feel, three you can hear, two you can smell, one you can taste. This is not distraction. It is re-engagement with sensory experience, which is the antidote to dissociation.
For racing thoughts and intrusive thoughts: defusion techniques from ACT (Acceptance and Commitment Therapy) teach you to observe thoughts as events in the mind rather than facts about reality or instructions to follow. "I am having the thought that I am going crazy" is different from "I am going crazy." That distance is learnable.
For the longer term: these experiences are symptoms of anxiety and they respond when the anxiety is addressed. The Do I Need Therapy quiz is worth doing if you have been experiencing these symptoms regularly. If feelings of unreality are persistent rather than episodic, a professional assessment is important to rule out other causes.
One of the most important things to understand if you are experiencing the feel-crazy symptoms of severe anxiety is that anxiety does not increase the risk of developing psychosis or schizophrenia. These are different conditions with different neurobiological mechanisms, different genetic risk factors, and different presentations. The fear of going crazy is an anxiety symptom. Actual psychosis involves fundamentally different experiences: beliefs that persist in the face of contradicting evidence, perceptions without external stimuli (genuine hallucinations), and impaired insight into the abnormality of these experiences.
The insight that anxious people have into their own experience, the ability to recognise that thoughts are intrusive and unwanted, that feelings of unreality are strange, that the racing thoughts are a symptom rather than a truth, is evidence of preserved reality-testing. People with anxiety worry about going crazy. People who are actually experiencing psychosis typically do not.
Derealisation and depersonalisation as occasional, brief experiences associated with anxiety episodes are common and do not warrant urgent assessment. However, professional evaluation is appropriate if dissociation is persistent rather than episodic, if it is occurring independently of identifiable anxiety episodes, if it is significantly impairing daily functioning, or if it is accompanied by blackouts, memory gaps, or experiences that feel genuinely beyond the anxiety explanation.
Depersonalisation-derealisation disorder is a recognised condition that can occur independently of anxiety, though it also frequently coexists with it. Professional assessment distinguishes between dissociation as an anxiety symptom and dissociation as a primary disorder requiring its own treatment approach. The Do I Need Therapy quiz is a reasonable starting point if you are uncertain whether your experiences warrant professional attention.
It is worth noting that some anxiety medications, particularly certain SSRIs and SNRIs, can themselves produce feelings of emotional blunting or mild depersonalisation in the initial weeks of treatment. If you have started a new medication and begun experiencing these feelings, this is worth discussing with the prescribing doctor. It does not mean the medication is causing permanent harm, but it is important information for managing the treatment.
Cannabis use is also frequently associated with depersonalisation and derealisation, both during use and after it, and can significantly worsen anxiety disorders. If cannabis is part of your picture and you are experiencing feelings of unreality, the connection is worth taking seriously regardless of how common or normalised cannabis use feels in your environment.
"You are not going crazy. You are experiencing what happens when the anxiety system runs at full intensity. That is a very different thing, and it responds to very different treatment."
