river fold?

[jba]

raise KdQd utg+1, next in is a very good live-style player who thinks you are a bit in the laggy side who cold calls, a couple more cold callers, blinds call.

flop 943 two diamonds
I bet, utg+2 calls, another call, blind check/raises, I call, utg+2 now 3bets, fold, blind calls, I call.

turn T club
checks around

river 5 diamond
blind bets, how insane is it to fold here?
