Maybe you should reconsider yourself? What did you do to be treated like that? Sometimes, a person is isolated for no reason, they just don't like you. I am also in nearly the same situation as you, there seems to be a wall of glass separating me from everyone. I insist that I didn't do anything wrong, I just lived my life but it still happened. so don't pay too much attention to bad things, do what you should and enjoy the life
