Have you tried other SSRIs for depression? Wellbutrin made me have hallucinations, and be quite a mess mood-wise. It's the only anti-depressant that includes a stimulant (I think). Which is a good idea, but I don't think they should be mixed in one pill.

I would say it sounds like you could be bipolar, but since the stimulant in Wellbutrin can make your moods unstable (i.e. causing agitation, hyperactivity, etc) you should probably just try another AD before trying a mood stabilizer...unless you've already tried them all (and I know most people have).
