I don't think your question is a dumb one. You're trying to help yourself. That's valid. The thing is, snorting Prozac won't do anything for you except burn like hell (your nose and throat). You won't catch a buzz or feel any antidepressant or anti-anxiety effects from snorting Prozac or any SSRI.

Something to keep in mind, btw...alcohol (including beer) is a depressant and can also cause miserable anxiety for some people.
