If I were you I would not cut yourself off completely, I have done that before and it was horrible. Have you explained this to any of your friends? I didn't for ages, thought that they would find it ridiculous and laugh at me but they were really understanding and I feel much better for doing it.

Everyone is meant for someone, whether its friendship or something more, you will find someone that understands you and you can be yourself with, just gotta keep on going and have hope
