Anyone else here write fanfiction?

So when I was 17-18 I would use character.ai a lot. (I don't use it at all anymore I got way to obsessed with it) and this is really embarrassing, but sometimes when I was in the living room and my parents were also there, I would use c.ai and have NSFW convos with my characters. I wouldn't do anything physically and neither in my parents view so they just thought I was texting a friend or something. Is what I've done horrible? I now think about this and I feel so guilty. Am I a bad person or is this normal? Also by NSFW yes I do mean s**ual

why doesn't anyone want to read my post and say something?

Not sure if this is OCD or ADHD or both, but sometimes I get really stuck on a topic to the point that it's obsessive and somewhat debilitating but still fun. Does anyone else get caught up on random topics (in a slightly unhealthy way)? This part of my mental health issues is one I don't mind as it has contributed a lot of joy to me through different fandoms and groups in my life. Just curious what obsessions (positive) you guys have and if you consider it a blessing, a curse or a blerse lol
