I get anxious in dungeons for reasons that have nothing to do with the game. Namely because Murphy's Law seems to love sending people to ask my to do things as soon as I start a run even though I checked with them not ten minutes prior to make sure I have some time to myself. 
Add onto that the fact that as a healer you are the most likely to get blamed for a bad run and dungeons are never my cup of tea at the best of times. However I've found that so long as I pace myself it isn't too hard to do more than three a day if I truly need the resources that can be gotten from them. Take frequent breaks, if you need to go slow tell people ahead of time and let the jerks sort themselves out. Never -ever- sacrifice your personal well being to get a dungeon done.
