I'm a loner too.  I tried to play the part of being socialable, but I don't seem to agree with anything anyone does.  I think most people are full of themselves.  I stopped trying to socialize.  I am what I am, and that's it.  I don't need to prove anything to anyone.  Just as long as you're happy being a loner, there's nothing wrong with it.  If you're uncomfortable in crowds, then don't torture yourself.  What's right for one person, may not be right for the next person.
i am such a loner, i hate crowds, what will i do to convince myself that i should interact with other people?
