As someone with CPTSD, OCD and Bipolar + psychosis, definetely mental health subs. Particularly suicidewatch.
From what I can see in your post history, you haven't commented on a single one. I think I know at least part of why they're dead. Maybe that's a Lemmy account thing where I can't see it though.
But I can't say that I have gotten a few responses when I've been posting. Not always live during a game, but the beginnings are there, considering it's still preseason.
