AK, KK, AA
I would suggest you try to see more Flops before being committed with these hands.
Please remember these are good starting hands and if the Flop is wrong the value of your hand melts in front of your eyes.
You may be thinking pocket A's is a better hand then it realy is.
Everyone gets there AA cracked.
It can be a hard hand to play.
Take a different aproach for a while and slow play it till the river.
if the board favors you then bet it like a bluff at the end.
If you get callers and your read is right you win Big.
If everyone Folds you should still have profit from others betting up to the river.
This will give you a better idea of how often the A's would win the pot and give you a better feel how to play them.
Relax and let your Cards do the Talking.
