I recommend finding some kind of activity you’re interested that forces interaction and sticking with it. My girlfriend likes dance, I do martial arts, a friend of mine is really into DnD, and there are plenty of other choices, music, improv, theatre, filmmaking, volunteering, language classes, whatever you’re interested in. Eventually you’ll make friends, you just gotta stick with it. And you have to already be interested in it, so that you WANT to go, friends or not.
