Its common for most ppl with bp to have "atypical depressions " eating more especially carbs sleeping more and ability for mood to be temporarily lifted from external factors
But its still a major depressive
Switching can happen. In my last bad mania i was manic for a long while would shoot down for days into black come back up to mania
I shot waay back down and was in mixed.landed in hospital
When i first got there i was a wreck that wanted to moan in hell in bed begging themvto drug me to sleep to escape the internal torture
As i was medicated i started switching one day euphoric manic awesome..mysteries of earth...next bed misery pain. Was on seroquel and started lithium. The day i went home i was hypo. Came right home went for a jog (i dont run lol) but in the next coming days lithium took over and stabilized me.
