Am I sick like everyone says?

I'm new here, so please bare with me. I've been labeled as sick and I wanted to get some different viewpoints.
A little background: I'm married with 2 lovely children. I'm also a salesman with a degree in Biology and Anthropology.
I have always had anger management issues. I am very prone to violent mood swings out of nowhere and I don't even know why. I am under huge amounts of stress. I cannot control my emotions very well anymore. I tend to hurt those around me with remorse, but what seems like a few minutes later, I have no care. I do catch myself believing that I have supernatural contact, that I can read minds. I think it sounds ridiculous, but then I am guilty of it. I am afraid of my violent snaps, because sometimes I have no recollection of them. I never knew I attacked someone. I tend to even forget that I am married or who my wife is. I truly do not remember attacking people or being violent half the time, but there are witnesses who tell me. Mental sickness does run in my family.
