For me, it's
boredom. Nothing is exciting enough when I'm manic (how many different jobs have I had?) and when the crushing depression sets in, there is nothing in the world that can motivate me to do anything other than breathe in and out all day.
The people/connection problems are a constant for me, too because everyone else is boring when I'm manic and I'm too boring to be tolerated by others when I'm depressed.
Thanks for the thread...it's
not boring.
