I could not, anywhere in this hand, muster up the strength to fold.

Should I have reraised the flop?

HOW do people fold stuff like this? You sit around and sit around and sit around with shitty cards and you get AK and you hit your A. Argggghhhhhhhhh

When the J hit on the river and he went all in I knew he had AJ, but I couldn't lay it down.

It's time for a break...
