Angry inside and cannot express myself!?

I am really angry inside and I cannot express my feelings. This is a contribution of how people speak to me or shout at me in an arguement etc. I cannot seem to express my anger. the only thing i find that helps is to drive really fast and aggressively. I dont want to do this but really need advice on how to let my anger out. Shouting does not help. I feel i want to destroy everything around me but do not have the heart to. I turn 28 soon and have never been able to find a solution.
