At my new work, I deal with very angry people. Often the anger is directed at me (sometimes for a mistake I made, sometimes for nothing I've done). I'm very thin-skinned and habitually let the anger hurt me in the moment -- dwelling on it later, how I could have done better, etc.
I'm working to observe such moments (goodness, and my own anger!), see how the angry person is suffering, and make my unconscious reactions conscious -- but any additional advice would be greatly appreciated.
