How do I get over my trauma?

I think you may very well may be depressed. Depression can happen even with out trauma or a difficult family. I would start with your school councilor. He can be an easy starting place and has young people and professionals at his disposal. Do not make things worse by thinking about hitting anyone. Do not act like the old step-dad. Do not lower your self to that level. At any rate there are things available at very low costs or government aid. Not wanting to have to deal with an uncaring person does not mean you fear her. It means you are grieving for your lost childhood and the little boy you once were. If it is hard for you to think about your situation that causes tears to come, that is angry frustration. A common thing that happens when no one listens or cares. Please do not worry and the councilor has men cry to him all the time. It is a sad part of a very rewarding job. Do not talk to friends at this point, it might lead to more embarrment that you do not need right now, Good Luck! You deserve it.
