I have this irl too, so I'm positive its social anxiety related. One tip is ignore notifications, another is don't log in very often and third maybe roll a bunch of alts so you never feel too attached to one name and its consequences, going to xth its unlikely you'll ever meet anyone here, so you'll be perfectly fine.
I can't quite use the 'they're all just bots in Eglin' line I do to get myself to post at reddit, then again I don't even like asking chatgpt questions, have to set goals like 'I need that resume generated by the 2nd' or 'I need to ask how to change legal name on hellsite by whatever day'. A digital version of the audience is naked that people say helps with speaking and no, it doesn't.
