Hey Dan,
I imagine everyone here has felt at times " like I don't fit in here." I know I have.
My mania starts off with a day maybe two that I feel "elevated" then it turns right into an ugly mess of self loathing, self harm
My depressions are combination of self harm and the inability to move or think.
I rapid cycle A LOT. So I often have a few days here and there between the swings that I feel "ok" for lack of a better word. Not great Not bad..
The best advice my T ever gave me was " Don't stress over what your next swing might be" It's taken me a while but I have forced myself to calm down and not stress about it. Yeah I have had some freak out days !! But it's a lot less.
Dan, you fit in here, even on the days you don't think so
