I am writing this from inside chronic autistic burnout that began with a traumatic year in 2024. I want you to know that upfront — not as a disclaimer, but because it matters. Because the words are harder to find today. Because I nearly didn’t write at all. Because that, right there, is exactly what autistic burnout does.

This week I had a meltdown because of my mother - in front of my mother for the very first time. After a lifetime of holding it together until I was alone, I just couldn’t hold it back. I sobbed and sobbed. I am sixty-something years old. It has taken that long for the mask to slip in front of her.  To let her see that I'm not the "confident, in control, reliable and capable person" she has always believed me to be the one she has leaned on for decades.  Some masks go very, very deep.

What Autistic Burnout Actually Is

Autistic burnout is not depression. I want to be clear about that, because for decades, that’s what I was told it was. Doctors, well-meaning and wrong, would listen to my description and reach for their prescription pads. But I knew. Even in the 1990s.   I had my ADHD diagnosis — but I didn’t yet know I was autistic. What I did know was that the word ‘depressed’ was wrong. I sat in a doctor’s office and said: “I am not depressed. I am burnt out. I cannot do this.” Nobody really understood. The concept of autistic burnout as a specific, neurological experience did not yet exist in clinical awareness.
​
Autistic burnout is a complete and utter collapse due to overwhelm. It is exhaustion that goes beyond tired — and I know tired. I have fibromyalgia and chronic fatigue. I am very familiar with physical exhaustion. But autistic burnout is different. For me it is primarily mental, even as it pulls the body down with it. It is what happens when an autistic brain has been running at full capacity for too long, masking too hard, managing too much, absorbing too much of the world — and finally runs completely out of fuel.

At sixty-one years old, I finally heard the words that reframed my entire life.
"You're autistic. There's absolutely no doubt."

For one week, I experienced the most profound euphoria I have ever known. I don't have to try anymore. I don't have to fix myself. It's just me. Then came the grief - wave after wave of it. "If only I'd known before."

I had already been diagnosed with ADHD at thirty-one, which had been a relief in itself. But the autism diagnosis thirty years later filled in the missing pieces in a way nothing else ever had. It explained everything. And it raised the question that so many late-diagnosed women ask themselves: why did it take so long?
​
The answer, I've come to understand, has everything to do with being a woman.
