Why oh why did I pick a priest?

I was late for tonight's run so I didn't really get to go anywhere. Was invited for Heroic Lady Deathwhisper (was supposed to be hard-mode). But when trash respawned, the officers decided to go back to regular mode and attempt the bitch again next week when people finally pull their noggins outta their sphincters, wishful thinking really. The rest of the night I was benched. Imma be honest and say I was thoroughly pissed off that I was benched, but well really what can I expect on being a 3rd healing priest and fighting against OP healing classes? I hate my priest right now...
