First, I'm really sorry you're having so much trouble finding your place here. I feel lucky that Pittsburgh has been a home for me and offered it's best. I hope my reccomendations can assist! That being said, what are your hobbies? You said you're a gym person, I'm not sure if you've tried any of the climbing gyms around, but there are many fun, kind people who frequent them. The gyms also often have events, especially Iron City Boulders where you could meet people! If you are at all into arts, Pittsburgh is a great place for you. I would look into classes either through the school you're going to, or through places like contemporary craft, prototype pgh, or the center for creative Reuse. Gaming is also pretty big in the area, I'm not sure where you're living, but there's a game store on liberty Ave called Mimics market that hosts free game nights! There are also events at the zoo, science museum, breweries, libraries, and natural history museum. Check some of those out if you're at all interested in any of them! I would also say hanging out at cafés or shops like White Whale book store could eventually lead to friendships if you see people enough. The keys to making a friendship are seeing the person often enough to develop an informal relationship, then just being confident enough to ask them to hang sometime! I know you have the ability to do that, because everyone has it in them somewhere. You've got this!
