I think you need to be on a working daytime antidepressant, so I hope you go back and manage to finish high shool. I know I would never go back to university unless I felt at least partially better. Try your best to work your way through it. I'm not sure what would be best in your case but there are anxiolytics, and quetiapine at least partially works for me. Try to find a good doctor who understands.
