I find having a job (even part-time, 24-32 hours a week) helps me to have a routine and a sense of accomplishment. It isn't a glamorous job but I get to work alone for the most part and at my own pace (I do aisle maintenance and stocking shelves at a large store). Getting a paycheck certainly doesn't hurt either! It definitely helps with my mental health overall although it can be a challenge at times.

Without a degree of any sort you will likely find it hard to get a job that you truly enjoy, but maybe you can change your goal to finding a job that you can tolerate? You could also seek part-time hours and shorter shifts so you aren't as overwhelmed. When I began my job it was 5 hour shifts. When I felt ready, I asked for it to be increased to 8 hour shifts. Nothing wrong with recognizing your limitations and doing only what you are capable.
