How long does it take for intense sustained emotion to kill you? Fury/being enraged/hatred. How long can a body take it before death occurs?

Would it be painless or painful? Would it occur swiftly or take a very long time? Once in the throes of it would there be no pulling back from it? Did you ever scare yourself because you got so angry/enraged/furious? How did it feel and did it ever happen again?
