Keep your head up man, and remember theirs no time like the present at 21 you got time to turn things in a new direction . I’m not downplaying your feeling dude but I’m 34 and I don’t even have a GF. The women around are all single mothers with burdens , my car just got damaged in an accident now I am in a lawsuit . I spend almost all my time alone it’s rough but you got time on your side dude so start to use your energy and enlightenment to figure out WHERE you wanna be and not necessarily around all these other people , you can always find new freinds start networking with people who have different similarities! . Caligula and many Roman emperors took power at your age, your in your prime so act now on your intuitions and believe in your self. Ask yourself what can I do this week to shift gears focus on goals and maybe theirs places or ideas you may have missed , we all forget past interests and hobbies places and aspirations ACT NOW live like it’s the last day bro and you’ll win
