I think I'm not lovable?

Hello, I feel like I'm unlovable…my family is generally very cold…we never really hugged each other. My mother lost hers at a very young age and was somehow quite cold towards us children, or rather, she never really hugged us or told us that she loved us…maybe it has something to do with the fact that I'm from the Balkans, where everyone seems a bit colder. The reason I also think I'm unlovable is that I've never been in a relationship (I'm 21), and I know that's unusual. But nothing ever happened, or I never found the right guy…and I feel like I'm somehow invisible to men, or not interesting…although I wouldn't describe myself as unattractive.
