A lot of people take it out on others when they're angry. That is obviously not a very good way to handle anger but it's easy, quickly gratifying, and very common. It's completely ok to be angry sometimes after something bad happens but there are good and bad ways to deal with that anger. Don't push it down and contain it that will result in a lot of misery and an explosion of anger eventually. That doesn't mean when you're angry you should react pig of anger and do something you'll regret. When you're angry talk to God about it. Tell Him why you're angry and let His presence and peace wash over you. When you sit and talk with God His peace starts to fill you up no matter what emotions you have going on inside. Being in God's presence is the best thing you can do, during all times really but, especially during hard, stressful, or angry times. The negative emotions we feel are all part of living on Earth and there is no way to get rid of them but there are ways to deal with them well. Give those emotions to God while you pray to Him. Surrender your control and give up those feeling to God so that you no longer have to carry them with you.
