I have experienced the same in recent years. Now, my doc thinks I am bipolar. They started me on antidepressant with initial diagnosis of MDD associated with GAD. That made things worse, and they took me off the anti-depressant, and that was worse. Now I start job number 7 (in 4 years) on Monday, so the doc said I was in mixed state with mania induced from taking the antidepressant, which is now associated with latent bi-polar that I had been misdiagnosed since the first MDD several years ago, and this episode just boosted it.

I am so tired of being the med guinea pig with my head being so f*d up, and now I don't know what's going to happen. I can't get stable. I am wondering if this is just a bunch of hogwash, yet I am desperate to get help.
