I dont know if your gamer or not but maybe take small steps like talking to people online while playing video games or this going to be hard the first few times just say hello to someone on bus or train they may or may not talk back if not your not going to see them probably again anyway.the first time you get a small smile and conversation is one of the best feelings in the world because you know you fought your fear that 1 time and succeeded.try old people LOL there less intimidating and more like to talk to you and have tons of life experience they want to share.
