My husband is going through a similar reexamination of his symptoms. Up until now, he's been diagnosed with recurrent major depression, but like you, has periods of agitation and anger. His angry periods are primarily in the spring, and after a moderate winter depression. His depressions take on a more "atypical" pattern (sleeps more, eats more, more lethargy) and he has tried numerous antidepressants that either haven't worked or have "pooped out" on him. He's 43 and this has been happening for years. We now think he may be more on the "soft bipolar" spectrum.

Someone in another thread had mentioned the work of a psychiatrist named James Phelps. He has done a lot of work with other prominent pdocs in developing a model of bipolar disorder that is more "spectrum" based rather than the discrete, clear-cut types found in the DSM-IV. His work seems to resonate with us and makes sense in the context of my husband's symptoms. Definitely bring it up with your new pdoc. Have you been on any mood stabilizers or just antidepressants? Even with someone with a clear-cut diagnosis, it can take years of medication trials to get the right mix.

If you're interested in reading more about Phelps' work, here is a link to his website: http://psycheducation.org/

I hope you are able to sort things out soon.

Edited later:

I just looked at your other posts, and it seems that you were already given a diagnosis of bipolar, so the "soft bipolar" context may not apply. But I did want to still share my husband's process of searching for the right diagnosis. I originally read your post to mean that you hadn't been diagnosed with bipolar, but had been diagnosed with BPD and were questioning that diagnosis. Sorry.
