Steward,
Just a note to say thanks for your post. I'm in the midst of a deeper depression than ususal, nothing seems to work for me either. For some time lately I denied I had bipolar2 cause nothing seems to work. I quit looking at sites such as these cause I have about given up. Years of this also for me; I'm 54 now. Now I don't hardly 'cycle', maybe a good day now and then. Summer helps though.
Said a prayer for ya....
