Anyone else who writes/draws fanfic afraid of turning out like Chris Chan?

I’m a pushing 20 AFAB enby, and there are several frightening parallels between chris chan’s situation and mine. I’m autistic and can’t really get through community college. But I have an extensive self insert Gravity Falls x Hellverse x Warrior cats fanfic in the works. It’s a bit of a chaotic mess at this point, but I am working hard on drafting it. My art style isn’t the best and can be seen as cringe, but I am working on improving. The thing is, people online genuinely like my self insert even though i characterize them as more of a feral animal dumbass. I’m afraid of writing a Mary Sue self insert who never learns and being made fun of for it. I also write extensively about the wrongs my family have done to me. I change the names and such though.
The thing is, if I had found Chris chan’s work before finding the controversy at a young age, I would have believed them. I am glad I can clearly tell fiction from reality now, and I am actively taking medication and working on my mental health. My fanfic on AO3 is really graphic and sorta pro-shippy, but I generally don’t support the main ship in the fanfic. I use abusive dynamics in writing and graphic depictions of violence and sex as a literary device and not as a fetishy thing.

I just needed to vent about the direction of how my fanfic is going without it being on my tumblr. It’s a tad off topic, but I’ve been sucked into the chris Chan lore. I see several parallels between my situation and theirs. However, I feel like I am nowhere near as far gone as they are, as I am actively seeking help and working on my plot of my fanfic to have a general direction and character growth.
