Kickboxing helps a ton. The other day the teacher congratulated me. I imagine i am hitting everyone that has hurt me in some way. For our mind there is no difference between reality and the imaginary. So its like i really hit them, got my revenge, and I can rest. I hope you find a physical outlet so the anger doesn't consume you inside - it can later make you sick. Write how you feel, burn the paper, exercise, take it out in constructive ways........ this was not your fault. At ALL.
