My own healer horror story doesn't have to do with incompetent players. I kind of signed up knowing that they would be out there. It's dealing with my own feelings of inadequacy during instances. "Stupid healer!" "You suck at heals." "I'm dead healer, WTF?" Not once has any of these occurred in my chat log, but it's what I think they are thinking when it happens, and it's what I tell myself when things go wrong. Feeling proud of myself for executing a well-timed mid battle rezz is erased by allowing myself to let the player die in the first place.

It's like there's this other gauge that no one else sees but me. When tanks dip below 30% and/or die, dps die, pet dies, I die, or witness mistakes on my part chips away at it. The lower it gets, the more of a failure I feel. I think most healers can relate to accomplishing an instance, but still like you totally lost. It's the worst. A lot of this game is me vs me.
