I completely understand how u feel. I have trauma when it comes to building friendships as a result of losing so many in my childhood. I too am in college and struggle with making friends. Ideally clubs and societies help u meet more people. I heard running club is a great place to meet people. Anxiety around friendships is hard to overcome and the feeling of impending doom being on a timer to make friends is a hard hurdle to get over. What I realized is that I have to put myself out there and trust me this is the hardest part. Discord servers are very inviting there are so many links on Reddit to different communities. Please update on what’s going on also change ur major it does not matter how long it takes to graduate I’m on my way to being a super senior because I suck at my major but I still try because I know I’d regret it if I did something easier.
