Get a book at the library about what is required for getting a claim approved for SSI or SSDI. Your age pretty much makes it impossible that you will qualify, in the absence of some terminal disease. (You can even look that up on line.)

You do sound depressed. Going to the mental health center in your area might be worth doing, even if just to find what you are, or aren't eligible for.

At your age, I was stuck in a low-paying job and getting nowhere. By age 23, I decided to apply for a one-year vocational training program. That improved my life a good deal. When I got half way through the training, I became real depressed and went to the family doctor. He put me on an antidepressant that helped me sleep and made me much less depressed. I finished the program and was doing quite well for a while.

This happens to not be the best time in our nation's history to be a young adult. I hear that lots of college graduates are waiting tables. That's why I recommend vocational training. Doing anything, though, is going to help you better than doing nothing. Habits you have now will color your future and determine your destiny. Good luck.
