No clue what i'm feeling

I'm feeling something or maybe it's nothing. Maybe I'm not feeling anything. I don't really know what to feel. I cant decide on an emotion so I am just emotionless. I know I'm feeling a little hurt, and lost, betrayed, forgotten, helpless, ignored, belittled, inferior, alone, looked down upon, judged, sad, angry, and there is more but I think you get the point. I am feeling all of these things but I cant figure out what the over all emotion is, what I am feeling over all. I just feel numb. I want to brake down and cry but I cant, I want to talk to someone but I cant open up. How can I talk to someone when I don't even know whats wrong? I wouldn't know where to begin and there is so much on my mind that I don't think it would ever end.
