Hello there, I just recently joined as well. Found out last week I have BP I and joined here a couple days later. Struggled with PTSD and MDD for years before that, though I guess I was always struggling with BP, but just didn't know it. I can relate to your high-functioning vs. dysfunctional perspective, though my high-functioning areas would be school and work, and dysfunctional social and hobbies. I try to keep up my main hobbies, photography and playing piano, but that doesn't always happen during my depressive episodes. Sometimes playing the piano when depressed just causes me to start weeping uncontrollably, as if making music is just too intense. Kind of a hindrance to practicing, lol. Well anyway, welcome to the forum!
