I was upset - in the past; for example, i was upset when I did this / at the time. I had been upset, that's the past in the past - to state that you were already were upset before the time you mention. I was upset at 3pm. I had been upset when I saw her at 3pm. That means you were upset before 3pm. I don't think many people say "I had been upset" to be honest.
