When I was younger I suffered from extreme loneliness. What I finally realized is that you must be comfortable with yourself, be your own best friend . I went out and got a part time job, which made me come out of my shyness. I started doing things that I liked to do and didn't worry about whether I had someone to share the experiences with, after a while I became more confident and talkative. I would do whatever I wanted by myself, movies, shopping, etc., the point I am trying to make is, that you must be comfortable with yourself and with your own thoughts and I guarantee your life will change. Mine did!
Minecraft is super fun and social. You can play the free classic and join multiplayer servers. It's how I spend most of my lonley weekends. You don't have to build or do anything you can just talk, but i recommend building and attempting to get ranked, even if you don't feel like you'd enjoy it, still give it a try! :) But you will eventually get passed this stage in life and find routine interests.
You need to find somebody you feel comfortable with and confine yourself to and just talk and release everything of how you feel. I'm truly sorry too for how you are feeling also I sure do hope you start to feel better too sweetie....
You should walk around with your head held high (confident not snooty) with a "yes I'm single and you are going to have to be pretty amazing to change that attitude" if that doesn't work find a person just as weird as you are (thats how i got my bestie) and try to be their friend
