I am sorry you feel so angry all the time, perhaps it is Satan working really hard on you to make you not feel the spirit so you won't want to go on a mission. Maybe he knows how much good you'll do, so he wants to stymie you now. One thing to remember is to realize that someone can only make you mad if you allow them to. You get to control how you see people and their actions, or reactions. I know it is hard.... I KNOW. But it can be done. I love you!
It's not that I'm mad. They hurt my feelings by saying and doing things that they know hurt me and then they don't care even when I bring it up to them. So then I get angry because I don't understand how someone can just not care.
