folding top 2?

I'm not sure why you called the flop considering you're crushed.

To demonstrate what I'm talking about, against a range of {55, JJ, AK, all diamond-diamond combos left in the deck} you're only 47.212% (as shown below).

Passive players don't often have a weak range when they call pre-flop then raise you on a board that slaps your range in the face.
