I believe I have the psychopathic behaviour?

Apart from very emotional people, most people can mask their anger, in situations where it wouldn't be appropriate to express it. Besides, if you look up any mental illness, you'll more than likely have mild forms of one or two of the symptoms, because mental illness is just a skewed version of what we call normal, rather than some totally alien concept. I think you're less psychopathic and more of a whinger.
