I think I'm either going through it or getting ready but when I told my doctor, the conversation went pretty much like this -
"Well, why do you think you might be starting?"
"Because...(thinking)...on any given day, I could line people up and slap them... or in the next five minutes... feed them soup."
He said "Oh"
"But then, it could be because most people just piss me off."

That was pretty much the end of the appointment.
