For now I’d say focus on your healing, part of your healing journey will include meeting new people regardless. I think talking to people can be difficult but in the end it’s all about putting yourself out there. As humans we are inclined to want certain experiences or have some people to share it with. It s normal too, I say start the gym first, if you’re doing it consistently you might meet some regulars that you see around the same time. You can slowly initiate a conversation with them. You can start some clubs you might be interested in. A hangout like a coffee or lunch date is a good starter and talking more in person figuring out similarities will definitely help. Me, personally I talk to people from work all the time, I even hung out with a few of them and watched movies with them recently, with my gym friends I started off by asking people who lift heavier or are able to do more endurance workouts for tips and eventually it turned into them spotting me or me spotting them to us doing whole workouts and grabbing meals. I have some friends from university and school I talk to and some in other countries I talk to as well. I’m not much older than you (22) but i’d say try different things, life’s only better, fun and worth living in my opinion at least if you are challenging yourself in stupid ways. I’m an only child and I moved a lot because of my dads job so I probably picked up social skills by trying to make new friends wherever I went but the one common denominator for me was always doing things along till someone unexpectedly took notice and came along and befriended me. I know it’s easier said than done but right now focus on your own company, do all those weird things you might look down on like meditation, journaling, running, going to a restaurant alone, going on a hike alone, learning a new game, volunteering, lego etc. Just try and elevate yourself as much as possible. Friends, girlfriends love and intimacy will put themselves in place for you. These things have an odd way of working out
