Is it normal to have angry thought attacks?

Lately, I have been the victim of angry and cynical thoughts. I am under a great deal of stress personally at the moment and my mind is starting to scare me a little. It comes in the form of attacks, like anxiety attacks but instead of thoughts of terrifying things, its thoughts of inflicting suffering on those who displease and or criticize me in any way no matter how small. These attacks can last most of the day sometimes and in a weird way I enjoy fantasizing about these things. I can however control my impulses when I am thinking this way and act normal but its mentally exhausting.

I have no history or mental illness, I am not a narcissist, there's no anger issues or violent tendencies in my past either however I was abused mentally as a child.

My friends would tell you I am a compassionate, funny, hard working person who loves life. That side of me is really taking a back seat these days and the "Hyde" in me is making frequent appearances... Does anybody else ever feel this way? It did help to write it down and express it.
