For me, it is a tie between this forum and my therapist, as I have no family or friend support. (I actually have no friends, unless you count my PC friends.) Everyone involved in my life has helped me logic through things that have arisen during the most challenging parts of my life. They've also helped me feel less alone and assured me that they'd be there for me no matter what, which is very comforting.

I do have other comorbid conditions, such as ADHD and GAD (and alleged OCD, but I disagree with that one). Struggle wise, I'd say there is actually a tie between my ADHD and BP, mostly because both of them affect my ability to concentrate at work and achieve what I want to achieve. But I do use Reddit for my ADHD concerns since the ADHD forum here is not so active...
