Yes, I feel like this sometimes... I just want to scream or yell at someone, or break something, but I never do, in the end.. not sure if it's positive or not. Anyway, I understand you, and I'm sorry I'm not a doctor, but I believe your anger is just a way to "react" to your feelings (some people use sadness, for example). I don't know... wish I had better advice, but just know that you have all my support
