I have a serious problem with wanting revenge. If anyone ever wrongs me, i have this strong rage and I begin thinking of ways to get back at them. Generally violent ones.
How do I cure myself of this? I have this ideology in my head that says if I don't retaliate, I'm opening myself up to be walked all over later on.
Advice from strangers on the internet won't help you much with dealing with RAGE. My armchair psychologist degree is telling me that there's a deeper reason for your anger though, but knowing nothing about you I have no idea what it might be. Try to figure it out and deal with.
Anyways, you should know that retaliating for the possible wrongdoings of your peers will actually open you to being walked on. Of course, you need to stand up for yourself, but you need to do that in the moment, not after the fact. Taking it like a sissy and then burning down their houses isn't standing up for yourself and will only make the people want to fuck with you more.
Go through the grieving process. Anger is a stage. But previous anon is right. You are provably hanging on to some serious old resentments if EVERY time someone pisses you off you go all psycho.
