((((DazedandConfused)))) I can relate to what you're saying. I'm gulty of that too, sometimes. My rule of thumb is to never say things that I wouldn't say face to face to the other person. It's not easy but it can work if you remember it. You can also try to vent your frustration by writing a letter to say what you want to say. It's great that you're acknowledging this behavior and trying to correct it!
