My suggestion is to bang out a note that spells it all out. Say what you have to say (anger or whatever else is bubbling inside of you) and then delete it and never send it. I have done this many times (and had I sent them I might have wound up in jail, lol!) but it does give you some sort of satisfaction just to say the words and see them in print. I cant say why exactly but for me, it was very theraputic.
