I don't really talk about it a lot, but I suffer from PPD (paranoid personality disorder. yes, diagnosed.) It hasn't really affected me on osu, you'll notice that I try VERY hard to stay drama free in terms of mapping stuff, as an active member of the mapping community since I don't really want this crap to affect me irl.
It sucks, but it helps that I'm aware of it. Even despite that, it can affect me. I still have severe trust issues, and it really feels like there's nothing I can do about it sometimes.
Despite it, I try to be social. It's hard. I spend a lot of time online because it's much much easier for me. The only other thing that I really allow myself to meet up with others for is smash bros (tournaments and stuff). I still go to class normally, but there are days where I just want nothing more than to stay in my room because it feels like the whole world is against me. It's gotten much better since high school though, so I try to stay positive
Slowly losing my mind. Hearing voices when people aren't around. Just the usual mental health of your average teen.
