Hi SF, congratulations on nearly finishing your post grad degree. That take a lot of determination when you're also battling mental illness.
Why not concentrate on improving your mental health and living situation now? Try to get a regular income and move somewhere less stressful. You've done so well up until now, and you can apply that to the rest of your life.
AA provides a great support network for people in recovery. Does your college have some groups you could go to?
I found relaxation exercises like deep breathing helped me deal with stress and get rid of cravings. Others have found exercise good. Whatever way you go, remember that drinking will make your situation worse.
