Some tips on dealing with parasocial relationships?

So far, I've unsubbed and unfollowed her everywhere, but since I don't have any close friends (not even online, long story short: a lot of my former online communities have fallen apart or changed for the worst, then I even forgot how to socialize online), all I have now is emptiness. Due to my circumstances, I don't have many option to socialize in real life (nor professional help, long story short: my country defunds public health care, especially the mental one, because "you can just pray instead"), and I also need some social rehabilitation on the online side (which kinda was a thing for a while on kbin/lemmy, probably I could continue it if I manage to find some mentoring).
