She's a nerd's nerd. Her special hobby is metal detecting. She lives in rural Ohio and works from home. She has zero friends (at least any mentioned) outside of the internet and, from the sounds of it, was equally isolated at school. I've rarely met somebody with such a severe lack of context regarding the severity of their own problems in relation to the problems of others.
It's quite depressing, because in a lot of ways she's far more functional than the average vtuber. Great at cooking, boring but well-paid job. Owns property. But she has the dreadfully toxic combination of desperately wanting a peer group/serious relationships, while at the same time being extremely socially unaware and inexperienced. Oh, and woman, so constantly self-critical and immensely set back by every failure or even perceived failure.
