Beleive you will be ok.

Take moments that you can, figure out what ok would look like to you, when youve got an idea of that, figure out what the path would look like to get you from where you are now to whatever ok is to you, and then when youve got an idea of that figure out the very first step you could take on that journey, and once you've got an idea of that, do it.

Then repeat.

Maybe your path is that you've determined you need school in your path to being ok, maybe you realize its not, same for Target, and the other things - feeling confident in your decision, by having a goal, a path, and an action will make it easier and more certain to get through difficulties and also, to be able to recognize the successes

By doing all this thinking, you'll likely be able to find the risky parts and flaws in your plan before you have to endure them, so you can plan around them and make things easier for yourself with preparation (think "this part could go wrong, ane then xyz could happen, ok, then if that happened, i could do this and be ok enough so long as i had abc" and then on your path, you make sure you have whatever abc is ready before you get to that risky part)

Burnout is rough, it takes serious work and change to recover from it and not get hurt again by it, this planning cycle of change helps me

Wishing the best

Do you live in a place (or go to a school) where you can ask for accomodations due to your disability? Not for getting disability compensation but for school?
