Too freudian for me. The root cause is I'm wired that way, or I learned it, because I act just like my dad. No hidden trauma in my youth. It will take constant, vigilant effort to catch those explosive overreactions. You're right about how quick they happen. Don't know if you also have depression, but I find that the old addage that bad thoughts attract other bad thoughts to be true. Breaking that cycle is important. I've ruined perfectly good moods just by letting one nagging thought start a whole chain until I'm down.
I'm finding mindfulness (meditation) to be more useful than therapy or medication, but I'm pursuing several avenues.
