Lashing out at others is definitely NOT a healthy way of coping with stress. If you become so angry at the people around you that you start yelling at them, it won't do anyone any good - they will just get hurt by your words and all of you may end up feeling even worse.
This doesn't mean that you should keep your feelings bottled up - however, it is best to focus your stress on other things, such as working out, or doing yoga, or something that you enjoy in order to relieve that stress instead of hurting your loved ones.
