I have the same problem! I am 24 years old but will be 25 soon. I made friends in college but they all live far away from me. I am currently living with my parents, and I feel quite lonely. Lately I have been reading a lot of self-help books and practicing yoga. They have helped me a lot and my sister too! I have never had any deep relationships either, not sure why. I am quite friendly but I tend to wait for people to talk to me. I actually joined some group organization but so far I haven’t made any real friends. I have a hard time connecting with people my own age and I actually tend to make friends with older people. They are much friendlier and I love them. Too bad young people my age aren’t as open and friendly. Anyways I think we were born in the wrong generation? Who knows?
