There is a book called "why am I still depressed" it touches on why some people find no relief from antidepressants. Some people can actually be bipolar but present as mostly depressed. If an anti psychotic is helping ...it's likely that is what is going on with you. I was diagnosed as clinically depressed for decades. Then I found that book. I talked to my pdoc about it and she put me on a low dose of AP. I have a lot less anxiety and depression now. I also sleep better.
