It starts by being honest about whatever it is that has set your emotions off in the beginning. Waiting for the emotions to release is smart, talk to them afterwards when you are calm. However, let them know how they have made you mad | upset | angry | etc. Do not talk with others about it first, go straight to them, and let it be between you and them. In a calm manner, talk it out, if possible. Sometimes this is all it takes for healing to happen, for the complete final release of the emotion. Sometimes it may not, but at least you will have had your say and you can move on regardless.
