Yes! I used to have a lot of OCs prior to the pandemic. Eventually, though, I became more and more comfortable with having just one that conspicuously resembled me in everything but appearance, because God forbid you have an outright self-insert or they'll be branded a Mary Sue. Nevermind that said OC was a self-insert in her origins, but I mistakenly phased out those aspects because I thought I would be a more "mature" writer if I did so. (How the hell I came to believe that is beyond me.)
Thankfully, in the end, I left the friend group that encouraged such a mentality, and after coming back from the Star Wars, I decided to go all-out and make said OC a full-blown self-insert like I did in that fandom. I'm still overcoming the shame stemming from all the hate I was exposed to and from my own intrusive thoughts about the matter, but it feels good to come clean. I was gonna say that you shouldn't expect me to publish any stories that feature my self-insert, but maybe I should do it as a form of exposure.
...also, my self-insert is totally not currently living in an alternate version of the Pokémon world where a lot of aspects of a certain Italian fan game are canon. It's like I fit in perfectly in there for some reason.
