The Hidden Exhaustion of Masking in Autism and Mental Health

Most people have, at some point, put on a version of themselves that isn’t quite real. The polite face at a job interview, the cheerful tone when you’d rather be anywhere else. For autistic people, that performance can be near constant, and it has a name. Autism masking is the effort of hiding or suppressing autistic traits to appear more neurotypical, and for a lot of people it never really switches off.

It can look like forcing eye contact that feels deeply uncomfortable. Swallowing the urge to stim. Rehearsing a conversation in your head before you have it, then replaying it afterwards to check you got it right. Copying other people’s facial expressions, scripting small talk, laughing half a second after everyone else because you worked out that’s what you were meant to do. The National Autistic Society describes masking as a strategy some autistic people use, consciously or not, to blend in and be accepted. It can get you through a school day or a shift at work, but it can also quietly take everything you have.

What masking actually costs

The exhaustion isn’t a figure of speech. Holding a performance together for hours, monitoring your own face and voice and body the whole time, drains a particular kind of energy that doesn’t come back with a single early night. When it builds up over months and years, it has a destination, and clinicians and the autistic community both call it autistic burnout.

Burnout here means more than feeling tired. It’s a state of chronic physical, mental and emotional depletion, often with heightened sensory sensitivity, a shrinking ability to cope with things that used to be manageable and a sense of losing skills you thought were solid. The team at South London and Maudsley NHS Foundation Trust describe how the relentless stress of masking can show up physically too, as raised cortisol, tension headaches and a kind of bone-deep tiredness, and how it leaves people far more vulnerable to meltdown or shutdown.

There’s a harder truth underneath all this. Research has found a direct link between camouflaging and poorer mental health, including a raised risk of suicidal thoughts, particularly among people who mask heavily over long periods. A cross-cultural study of autistic adults in the UK and Japan found camouflaging associated with greater anxiety and depression and lower wellbeing. None of this means masking is a character flaw or something a person chooses lightly. It’s usually a survival response to a world that hasn’t made much room for difference. But survival has a price, and the bill tends to arrive all at once.

Why so much of this gets missed

Part of what makes autism masking so damaging is that it works. It works well enough that the people doing it often go unrecognised for years, sometimes for most of their lives. This is especially true for autistic women and girls, who are more likely to internalise their distress rather than show it outwardly, and who use camouflaging strategies effective enough to fool diagnostic systems and, sometimes, themselves.

When someone finally does reach mental health services, what professionals see is rarely labelled “exhausted from a lifetime of pretending.” They see anxiety, depression, emotional ups and downs, an unstable sense of self, perhaps self-harm. Without an autism-informed eye, that pattern can map neatly onto other diagnoses, and people are frequently misdiagnosed with conditions such as emotionally unstable personality disorder instead. The treatments that follow can ask someone to do even more of the social and cognitive work that wore them out in the first place, which helps no one.

The overlap with psychosis

There’s another layer that deserves care, because it’s so easily misread. Autism and psychosis share more ground than people expect. The two have been clinically and historically tangled for over a century, and modern research points to overlapping genetics, brain features and symptoms. Studies suggest autistic people are several times more likely to develop schizophrenia than the wider population, and one review found comorbidity figures reaching as high as around 35%.

That overlap cuts both ways, and it’s where the autism and psychosis overlap becomes a genuine diagnostic puzzle. An intense special interest can be mistaken for a delusion. Social withdrawal and flat affect can look like the negative symptoms of psychosis. Sensory experiences common in autism can be read as hallucinations. Yet researchers comparing the two conditions phenomenologically note that the unusual beliefs an autistic person holds are often transient and rooted in a distorted reading of social situations, rather than the sustained delusions seen in schizophrenia. They are distinct conditions that can also genuinely co-occur. Telling them apart, and spotting when both are present, takes a proper developmental history and time, not a snap judgement in a crisis.

For someone who has spent years masking, the danger is a cascade. Burnout tips into crisis, the crisis is misunderstood, and the support that arrives is built around the wrong picture of what’s happening.

What good support looks like

The reassuring part is that the antidote to masking is not complicated in principle. It’s an environment where you don’t have to do it. Calm, predictable, low-arousal surroundings. People who understand autistic communication and don’t treat stimming or directness or a need for routine as problems to be corrected. Space to be, without an audience to perform for.

Getting the right support genuinely changes outcomes. A study of autistic adults in the UK found that receiving support was a positive predictor of quality of life, while having an unaddressed mental health condition pulled it down across the board. This is exactly the ground that good supported living for autistic adults is meant to cover, especially for those whose autism sits alongside a mental health diagnosis.

At Northern Healthcare we support people with a primary mental health diagnosis who may also be living with autism as a dual diagnosis, building each support plan around the individual with input from a multi-disciplinary team. That includes the small things that make a place feel safe enough to drop the mask, recorded alongside the clinical detail, because knowing which environments someone actually feels comfortable in matters as much as any assessment score.

If there’s one thing worth holding on to, it’s this. The tiredness so many autistic people carry isn’t laziness or fragility. It’s the cost of a performance that should never have been required in the first place. The goal of real support is simple: to make the mask unnecessary, so that the energy spent hiding can go into living instead.
