My advice is to find your Myers Briggs personality type. It is likely that people who will stay as your friends are those who have at least 2 similar traits with you. Also, it would be great to just have conversations with people who also have similar interests in conversation. It could be it politics, economics, philosophy or the latest electronics.

I have very few friends and I stopped trying to fit in to society after I graduated from university and I am very much happier now. Be yourself.
