There are degrees of upset. Sometimes there are just annoyances and then sometimes there are rages.
I usually try to find out why I am reacting so strongly to a situation. If some one had been deliberately mean to me; saying mean or bad things to me-it makes me sad
Sometimes you have to tell people they have upset you-maybe they don't know what they said was mean or unfair. "why would you say such a thing?" I ask. It gives them a moment to think about what they said.
Sometimes the hurt is enough to end a friendship.
Sometimes I feel like throwing something. Like shoes, a book, and bouncing it off their heads. Reacting like that isn't always good. Sometimes my emotions are so strong I am sick to my stomach and want to vomit.
Sometimes I think its their problem and ignore what they said. Sometimes people can be stupid and childish.
