It's my biggest leak, I've posted so many hands, and still...

I don't know how to get away from overpairs on a safe flop against an unknown.

I 3-bet my big pockets preflop, get cold called, make my c-bet on a safe board and get flat called there. Now I'm lost. Most of my stack is in the middle, and I have no idea where I stand. One bet later it's all in and my hand is crushed. I'm just totally at a loss in these spots. Do I just have to chalk it up to variance, or do I have to slow down when someone takes my 3-bet in stride?
