No stranger to mood swings. It has caused me to be incorrectly diagnosed with bipolar II a long time ago. For me, my mood changes by triggers not a chemical imbalance. For me it's not really a mood disorder, but more of a personality disorder. I can on some days experience the whole spectrum in just one day! I even get really super elevated hypomania and some times even grandiose feelings, but I am not bipolar. I can go from deep depression to anxiety to anger to paranoid to argumentative to quite to talkative to suicidal to homicidal. For me it's a personality disorder. Usually I only cycle thru 2 to 3 a day but can and do go all over the map some times. I hate it. I don't think more rapid then this is possible nor would I want it any more rapid. I'd like to stay at my baseline, always.
