I have no advice to offer. But I'm 33 and I haven't had friends since I graduated highschool. In highschool I had 3, 2 were kind of close, and one was the friend's older sister who was nice.

I don't know where to meet people who I could be friends with x] So, I still have none. Lonely isn't fun, so I truly hope you find some nice people and make some friends Best of luck.
