Somewhere in the world there is someone like you. Maybe not identically like you - but incredibly similar to you. But most people described as 'loners' have fallen into a set category in life where they assume no one really wants them around - hence why they are loners.
The truth is that we do this to ourselves - with over six billion people on the planet, how egocentric can we be to honestly believe that there isn't a single person even remotely like us out there somewhere!
The first step is admitting you have a shot at real friendship somewhere. The second step is finding people like you - starting with your hobbies and interests. You don't have to rush things, in fact it's probably best you don't. And there's nothing worse then pretending to be somebody you're not. Just meet up with people like you and relax. God help you, you might actually enjoy yourself.
