How to deal with loneliness?

I live in a small village without any possibilities of social interaction. I live with my abusers, and I don't have any relation to them (I barely even speak to them). I have few friends, but most of them are fading away as they are getting partners or family. I am left all alone without any possibilities to finding any friends whatsoever.

I always wanted to have a close circle of friends who'd be like my family, but I realised that it's a non-realistic dream because friends and everyone else in society focus only on creating a family or having a partner.

I am introverted, and I like spending time alone, but the loneliness does get cripling at some points. How do you deal with loneliness?
