I can relate! No uterus, just ovaries also. I personally don't think its all hormonal. I have rapid cycling bipolar and I act the same way. And I know for me its my bipolar. I just want to put my head in my hands and scream! I notice my cycle. I take notes, or used to. I know my "signs" of hypomania and depression. Major anxiety, depressed, then angry, then I get crazy happy and so on. Through therapy and a great psychiatrist, and 17 rounds of ECT I'm learning what is what. But I haven't felt good the last few days. It sucks. Plain and simple. I hope you find your trigger (s)!
