He slept.
Every afternoon after school, he slept.
Not the quick kind of nap teenagers take when they’ve stayed up too late. This was something heavier. He would come home, drop his backpack, disappear into his room, and sleep for hours. And when he woke up, he didn’t look rested. He looked flat. Drained. Like he had been carrying something all day that no one else could see.
We thought it was sleep. He had never been a great sleeper. So we bought vitamins. We adjusted bedtime. We tried routines.
But looking back, it wasn’t just lack of sleep.
It was anxiety.
At the time, though, I didn’t see it that way. I saw exhaustion. I saw irritability. I saw a teenager who didn’t seem interested in calling friends or making plans. And if I’m being honest, that part hurt the most. I thought if he just had more friends to talk to, more weekend plans, he wouldn’t look so flat all the time.
I didn’t yet understand how much energy it took him just to get through a school day.
When Anxiety in Autistic Teens Doesn’t Look Like Anxiety
We tend to picture anxiety as obvious. Racing heart. Refusing to go somewhere. Tears. Visible distress.
But anxiety in autistic teens often hides.
It looks like staying up too late perfecting a project no one else will scrutinize that closely.
It looks like rereading instructions over and over because getting it wrong feels unbearable.
It looks like needing to control the timeline, the outcome, the details.
It looks like snapping at home — not because they don’t care, but because they’ve used up all their control for the day.
And sometimes it looks like sleeping for three hours after school and still waking up tired.
That’s not laziness.
That’s a nervous system that’s been bracing all day.
There were moments when the anxiety cracked through.
Usually around school projects.
He did very well in school. On paper, he was thriving. But when a long-term assignment was given, something shifted. He wouldn’t start right away. Or he would start and get stuck. Days would pass. Then suddenly the deadline felt enormous.
By the time he came to me, he was already behind. Panicked. Frustrated. Sometimes angry.
“I don’t know where to begin.”
Which wasn’t really about beginning.
It was about not being able to see the whole thing at once. Not knowing how to organize it. Not knowing how to break it down. And underneath all of that — a fear of not doing it perfectly.
For him, anxiety often showed up as control. Not bossiness. Not defiance. Control over details. Over timing. Over how something would turn out. If he could control it, he could quiet the uncertainty. And uncertainty was the hardest part.
We’d end up working late into the night.
I felt protective and exhausted and sometimes frustrated — all at the same time.
But what I didn’t understand then was this:
The anxiety wasn’t about the grade.
It was about control.
Sometimes the anxiety didn’t sound anxious at all.
It sounded existential.
“What’s the point of all this?”
“What am I doing here?”
“I don’t want to be here anymore.”
Those words are terrifying as a parent.
We worried about depression. About suicidal thoughts. We got him into therapy. We tried medication. Some of it helped a little. Some of it didn’t seem to move the needle at all.
But looking back, I can see something else layered in there.
When a teen spends all day performing — managing expectations, masking differences, trying to get everything exactly right — it takes an enormous amount of energy. Eventually, that energy runs out. And when it does, what’s left can feel like emptiness.
That emptiness can sound like hopelessness.
And sometimes it is.
But sometimes it’s anxiety that has burned through its fuel.
The Cost of Performing
When anxiety lives mostly inside, it can be hard to recognize.
Good grades hide it.
Responsibility hides it.
Politeness hides it.
Compliance hides it.
Teachers may see a capable, hardworking student. Parents may see a teen who crashes the moment they walk through the door.
Both are true.
The cost of holding it together all day often gets paid at home — in sleep, in irritability, in flatness, in silence.
What Helped (Even If It Took Me a While to See It)
Looking back, what helped most wasn’t forcing more productivity.
It was permission.
Permission for him to rest after school without guilt.
Permission for me to stop comparing his weekends to his sisters’.
Permission to accept that exhaustion didn’t mean failure.
Permission to break big projects into smaller pieces instead of waiting for panic to hit.
Breaking projects down helped him.
But letting go of some of my expectations helped both of us.
When I stopped trying to “fix” the flatness and started respecting the energy it took him just to function all day, something softened. Not overnight. Not dramatically. But steadily.
I also had to face my own anxiety.
Was I doing enough?
Was I missing something?
Was I letting him off the hook?
Would he regret this later?
Those questions can spiral just as fast as a teenager’s.
But anxiety doesn’t ease when you add more pressure.
It eases when someone feels safe enough to exhale.
And sometimes that someone is the parent first.
