FYI: My doctor, friends, and family are all pretty sure that I have both ASD and ADHD, and I have been working on getting an official diagnosis.

I think my burnout started to happen right after spring finals. I was taking Calculus 2 and Physics, and I studied from 9:30 am to 9:30 pm at school almost every day of the week. I virtually abounded my social life, and despite working so hard at school, I would barely get a passing grade in both classes.

After finals, I lost my ability to do any logical or critical thinking tasks. I can no longer work with numbers, basic programming, and basic math. I have lost all interest in the things I like doing, and I am just bedridden all day long. I struggle to do my laundry, shower, make food, brush my teeth, etc.

I would maybe be able to play 1 or 2 hours of video games, then I would be drained as if I played all day, and I would need to go back to bed. Its the same when I watch a couple youtube videos, I would feel overwhelmed and then I would go back to bed. This is been my life for the past couple of weeks.

I don't feel sad or depressed, but I do feel lonely. I want to go back to hanging out with my friends and doing math, physics, and programming. I also want to go back to reading and doing my projects, such as building my own NAS and other art/drawing projects. However, I can't seem to do anything besides lying in bed all day.

Is this really what autistic burnout looks like? I have spent time in nature and forced myself to hang out with my friends and discuss my problems. I have gone on walks, hikes, and cycling, and I even tried going to the gym and dieting, but nothing seemed to work.

What am I doing wrong?
