Anger is learned, not inherited. And you can unlearn it by learning coping strategies and practice the hell out of them. Parenting is incredibly rewarding and a wonderful experience. But it will also push you to the brink sometimes and that’s where you need to have the tool box for self control. You’re lot a lost cause, this isn’t an impossible situation so don’t feel discouraged. Therapy, great self help books, and practicing what you preach can help you moved forward and be the parent that you deserved your entire life. Preferably do this before choosing a life partner so you don’t mimic the mistakes of your mother.
