Nitty.. i would not go so far as to say he is a coward. He is young. Hell, i wish I had the stones to contemplate leaving when I was still living at home. I would say he is inexperienced at worst.... not a bad thing at all. He is coming here for advice so good for him.
Get out bro.... you have little (relatively speaking of course) to lose. If you get out now you will never regret it! Dont allow your mother to shun you and sorry to say it but your friends are not really your friends if they shun you. Good luck... NUKE THEM!
