There might be a little too much of a catastrophic mentality in your posts here, Charactor. What you have talked about are all items that one should be aware of, but being ruined for ever and losing your sense of personality and encouraging someone to stop their medication on a forum like this is a little much. A "I am not your doctor" disclaiming is probably not enough to cover those suggestions.

Anyhow, to the OP: Are you bipolar by any chance? This sounds like it could be a bipolar cycle and if you are bipolar it seems to be common practice to be placed on a mood stabilizer before taking anti-depressants. You could be feeling worse or more anxious if that was the case, due to the lack of mood stabilizer.

Wellbutrin is also known for increasing anxiety, or at the very least is poor at addressing anxiety. It is great that you have pulled out of this depression. For me, however, I will find a pattern of feeling less depressed, but more anxiety, that I believe plunges me back into depression. It is all about working to solve every symptoms to reach stability, because solving only one thing, the problem of another can probably make the first thing came back.
