Most people expect anxiety to reduce when things are going well. For many anxious people, the opposite happens: a period of calm, a piece of good news, a successful outcome, or a positive life event produces not relief but a new wave of anxiety. If this has been your experience, you are not ungrateful, neurotic, or broken. You are experiencing a well-documented anxiety pattern with a clear psychological structure.
One of the most consistent drivers of anxiety during good periods is that positive circumstances raise the stakes. When things are going poorly, there is less to lose. When things are going well, there is a great deal to lose, and the anxiety system registers this clearly. The better things are, the more conspicuous the potential loss becomes. A good relationship is something that can be damaged or ended. A successful period at work is something that can be reversed. A period of physical health is something that can change.
The anxious brain does not experience good fortune as relief. It experiences it as a new vulnerability. More to protect means more to worry about losing. The threat-scanning, which is the default mode of the anxious mind, simply finds new material in the good circumstances rather than fewer threats.
People who have lived with chronic anxiety often develop an unusual relationship with calm. Vigilance, worrying, and hyperarousal become familiar and, in a perverse sense, comfortable. They are the known state. Calm, security, and the absence of immediate threat are unfamiliar, and the unfamiliar triggers its own form of anxiety. The nervous system interprets the unusual quiet as a sign that something has been missed rather than as a genuine absence of threat.
This creates the counterintuitive situation where feeling safe feels more frightening than feeling anxious. The chronic anxiety becomes the baseline, and any deviation from it, including in the positive direction, produces disorientation and vigilance about what is about to go wrong.
For people whose anxiety is accompanied by low self-esteem or shame, good fortune triggers a specific form of anxiety about deservingness. The positive circumstances do not feel like something that has been legitimately achieved or that belongs to them. Instead, they feel like a mistake, a gift that will be discovered to have been given to the wrong person and subsequently reclaimed. This produces the anticipatory anxiety about exposure and reversal that makes good periods feel more like a countdown than a resting place.
This pattern overlaps significantly with impostor syndrome: the persistent belief that success is undeserved and that exposure is imminent. The anxiety and self-esteem article covers this in depth.
The colloquial description of this pattern, waiting for the other shoe to drop, captures its essence precisely. The anxious mind, trained by experience or temperament to expect threat, interprets periods of calm not as genuinely safe situations but as the pause before the next problem. The vigilance does not reduce during good periods. It redirects: scanning for the thing that must be about to go wrong rather than the thing that is currently wrong.
This is reinforced by confirmation bias: any small negative event during a good period is taken as evidence that the anticipated reversal is beginning. Any continued good fortune is taken as evidence that the reversal has merely been delayed, not avoided. The pattern is self-sealing because it cannot be disconfirmed by continuing good circumstances.
The most useful reframe is recognising that the anxiety during good periods is not evidence that something is actually about to go wrong. It is evidence that the anxiety system has been calibrated by chronic stress to treat calm as suspicious. The anxiety is a symptom of the underlying pattern, not a reliable predictor of imminent threat. Noticing the thought "this is too good to last" and identifying it as anxiety rather than prophecy is the first step.
Deliberately practising engagement with the present good circumstances, rather than using mental energy to scan for what might end them, is the practice that gradually recalibrates the nervous system. This is the core of mindfulness approaches to anxiety: not the absence of anxious thoughts, but the ability to return attention to the present rather than the anticipated future.
"The anxiety during good periods is not a sign that something is about to go wrong. It is a sign that the anxiety system has been trained to treat calm as suspicious. The solution is treating the anxiety, not finding the threat."
