I used to be very aggressive in general, and I almost always had homicidal ideation. For instance, if someone on the road cut me off, I would think, "if I had a gun, I would shoot this stupid f***ing asshole right in the f***ing head. I wish I had a f***ing gun right now. He would regret everything he did."

The aggression was greatly reduced once I titrated my Lamictal dosage up. So, maybe see what you can do about your medication? I was pleasantly surprised with how simple it was to reduce my aggression. Sometimes medication is all it takes, although you might want to try working on it in therapy too.
