I was in a situation very similar to yours. I wouldn't say I was quite as hardcore as you, but just a by a smidge. I was a cutter, avoidant, dissociative, uncomfortable socially.
The answer your looking for isn't there. Do you really want to live this way forever? The only way to be better is get outside your comfort zone.
It doesn't have to be drastic. I took baby steps for 3 years, now not only can I look people in the eyes, but I also enjoy going clubbing and have a healthy married life too. It will never be easy, but it will get easier.
And it is worth the tears and fears. I, for the most part, have finally found peace and happiness in my own skin. I want you to feel it too!
I learned this in health class a while back, but its like a health triangle. There's physical health, mental health, and social health. If you don't make them all balance there will be something wrong.
Right now your health triangle is off balance and isn't right, you need to figure out whats causing this, I think there's a deeper problem to this. Best thing to do would be tell your parents. You can go to a doctor or counselor, they can help you!
So don't be afraid:).
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.
