No, there’s nothing wrong with you.
One of my close friends (originally online only) has a similar problem and early on she even got me thinking she was angry at me just from the harshness of her voice, but turns out that’s just kind of how she sounds and our group of friends accept her. She prefers her online persona, though, since she does hate herself and how she looks. I think she gets a lot of self loathing from her strict, stressed out single mom.
I think her online persona helps her get over it. A “white vtubers” in your case could maybe help get a load off. Give yourself some balance. There’s something to be said about online friendships since they often start with the written word, and once you find people who like you for who you are, it’s not hard to slowly explore your own self identity. It’s a long road out of self loathing, though, and I hope you can find people you can confide in as my friend found.
Come January, that list is gonna be full of really, really weird choices for President.
