No interest in anyone

Past year especially I've lost interest in everyone including my closest friends, I feel lonelier than ever and I don't know what it is, just depression?

I really want to want to meet new people but it's just not happening, part of why I really want to is my friends all have either left the country or are leaving and also I'm single af I want a gf.

Btw I've never had issue meeting people or making friends it's just that I've had 0 interest the past year
