The “friend’s” behavior sounds very immature and “high schoolish”. Nobody needs that. It’s unfortunate that this has happened but try to press on. I agree that it’s not too late to make friends. The previous poster gave you some great advice and the only thing I have to add is if you have time for a job, that might give you an outlet as well as a place to meet people. It is true - “the time to meet new, interesting people never ends.” I love that quote! Hang in there.
