I used to have issues with frustration building and building until it became ANGER. It was never directed at people usual happened when I was doing what should have been a rather simple task and it JUST WOULDN'T GO RIGHT.

The thing that helped me is therapy, I learned to identify this as a process, learning to see the process as it was happening, recognizing when this "process" was starting and learning to stop in the early stages when it is still manageable.
