I think its reasonable to expect to lose AA hands once in a while. You are only about a 90% favorite for any given hand and in this case you had two hands in. Perhaps you should have resraised PFR but in any case you will still lose them.

BTW, tilt is a difficult thing to control. Maybe after a loss like that you should just make it part of your stratey to stop play for 15 minutes and do something else.
