I have shared your frustration, but have finally found a happy balance. Mostly because i've finally accepted that it's ok, that not having a ton of friends does not make me a defective human. What really helped me was the following quote: "the surest way to be a fool is to attempt to be something you are not." in the struggle for outside acceptance, it can be easy to lose sight of who you are, what you actually want to fit into.
If you are trying to join a group of people with whom you don't genuinely share an interest/connection of some kind, you're bound to fail from the start. Don't force it. Take some time getting to know you, and don't put yourself down for being a loner -- there's nothing wrong with you.
Learn to be happy/have fun with yourself, and you'll be better able to share good times with others. In my experience, depression is the real friendship killer. When caught in a major depression, your perspective of the world is completely off.
The easy smile of a potential friend becomes a leering jeer of ridicule. You try a cheery hello and it comes out sounding like eeyore. Unfortunately, to a certain extent, the old saying "when you're smiling, the whole world smiles with you" applies when you're frowning too.
It can be very hard to change the mind's patterns of thought, especially after 10 years of practice, but if you can begin to think positively, to only allow yourself to think about the good in your life, you may find a way out. Another thing to think about--- though it's a solitary situation, there are many people who feel outcast by society. Perhaps you could keep your eyes peeled for somebody feeling just as low as you, and cheer each other up.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
