I am BP1, and lived my life around the disorder and still felt it progress to
a psychotic breakdown. I would say that as my body aged and couldn't recover from severe episodes, it got way worse for me. The moods I could handle, the craziness of starting over was what really wore me down. The mania of BP1 is really the destroyer. Depression is hard, but I never wake up on a different continent. Also, google 'kindling,' that is the word for accumulative bipolar.
