Depressed and lonely

I barely have any friends I only have 2 friends and a lot of girls I’ve never talk to before don’t like me they just don’t like me and I have a boyfriend and he has nothing to do with me not having any friends he has loads and he doesn’t stop me it’s just that everyone I met just wants to get drunk sleep around and I don’t judge people that do but I just feel like no one likes me and me and my boyfriend were talking about having a wedding and how his friends would be there and his family then I just pictured my side of people in the wedding it would only be my small family and my two friends as brides maids I feel like a loser
