It is not our role to advise you on this kind of problem. But having read what you say, there are some things that can be pointed out:
To have friends, you must make friends - show an interest in other people and what they like to do. Your signals are all that you want to be alone and do not like people much.
If you want to make a career of writing video games - isn't the field already rather full? - look for a college which offers a course on this and transfer to it. If that is your ambition in life, then look for a better way of achieving it than sitting playing games all day [proven to be bad for the mind and the psyche]. And surely even now you need maths for computer work?
