I Have Anger Issues And Cant Control My Actions

I dont want to hurt the people I love , I say and do mean thing just because I am not happy or I am stressed out, I have no patience, I dont know how to be a better person, I grew up with my mom stressed out yelling and hitting us, she was a single mom of five crazy kids, at one time we were all teenagers ages 11-15, so I know she did the best she could, but nevertheless we are all screwed up, I dont want to make my kids the same way, I need help to stop this from happening to my kids I dont want hurt them and make them screwed up in the head. I dont know what to do.
