I know the feeling you're describing.
My suggestion is that you try getting into meditation. Give it an earnest attempt and don't get discouraged by the initial frustration that tends to surface when you start it (I had been going on and off practicing it for years since it was so hard to make it a daily habit, but now when i've managed to keep at it have I noticed that it really fucking does help with my mentality).

I'm not as prone to anger or succumbing to other negative emotions anymore ( the negative impulses still occur but they are MUCH easier to handle and observe objectively).

I really recommend it man.
Combine it with a bit of yoga and you'll be a happy camper.
