Fear of missing out

I don't go out I don't have friends and I don't do nights out. I'm 21 and everyone else my age goes out partying, drinking, going to clubs. I mean I'm working full time atm and studying part time for a law degree so even if I did have friends or a bf and all that I just don't have the time. But I feel like I'm missing out and that I'm a loser because I don't do all of that. When people say "oh don't you go out partying" I just feel pathetic because I don't, more often than not I just have a bath and chill out in front of the TV 😓
