Martial arts: Learning one of the martial arts could be very helpful in this regard. You will need to go to a website to learn about other options that may or may not involve psychotherapy depending upon the severity of the problem.

Psychotherapy: Find a reputable psychotherapist to talk about the impact you feel year after being bullied. Feelings of impotence, rage, and shame will most likely come to the surface in a non-judgmental and safe environment. Talk to someone. Keeping it inside only aggravates the emotional problems you describe.
