Was it dumb of me to gamble on this draw?

[KSOT]

Nut flush draw and gut shot straight draw against 2 bigger stacks than mine that I figured would both put their money in. I figured I would be getting 2 to 1 on a better than 2 to 1 draw. But now I'm having second thoughts about my last flop call. My turn call is unquestionable IMO. What do you think?
