Queasy feeling with flopped set

[antidan444]

I almost got away from this once it was two back to me capped on the river ... I had a gut feeling from the turn action I was beat, but the "don't fold in a big pot with a big hand" mantra was pulsating in my brain. Did I take this too far? Or is this just one of them hands you have to suck it up and put the bets out there?
