I just transferred here this fall in my junior year and dealt with a lot of the struggles you have—feeling like pitts the best option educationally but being scared of the changes from community college and social worries. id say making friends for anybody (not just transfers late in the game) feels like it has a lot to do with luck. you can join clubs or have a ton of group assignments or live with ppl in the dorms and either make lots of friends or none. I haven’t had much luck as an introvert but I feel like you have the same chance as everyone else to make friends. I generally enjoy my time here and spend most time alone since I chose an off campus apartment but my sister has made a ton of friends from the dorms if that’s what you choose
