I'm sorry t/Pdoc is leaving. That sucks. I know that in the past when I have gotten angry out of the blue it is usually that something else had made me angry and at the time it happened I didn't know it. It then popped up in other places with me being angry and I had to try and figure out what might have happened, who knows how long ago, that made me mad. Now I am much better as I often know when I am angry at the time so it can be addressed. It has been a long process going from being angry literally weeks after an event to knowing I'm angry when something happens. I'm still working on what to do at the point in time when I get angry and there are times when I still don't know right away. Could there have been something in the past recent or more long term that made you angry but you were not able to express it? Good luck.
