Talking about your deep feelings is necessary so get someone to help you sort them out. An anger management class might be helpful also. Al Anon gives good support if you have family members caught in addictions. And if you are having problems with disciplining your children, take a parenting class. I recommend taking a parenting class when your child is two and then another one when your child hits adolescence.
Some parents take several classes to keep up their parenting skills.
So if you consider yourself an angry person, you probably are. Think about giving yourself a wonderful gift. Get some professional help. You can't do it by yourself. Talk it out with someone who cares about you as a person.
