Considering that I did play this hand at all, what would you do next?

This is a tough one, but I think you have to call here. There are only three cards in the deck that have you beat.

As a side note, with a flush draw type board combined with the fact that you are the first one to bet and there are quite a few people in the hand (so a greater possibility that someone is on a flush draw), I would have bet bigger on the flop. Probably something like 250-300. Your hand is very vulnerable to, not only a flush, but a higher straight. Go ahead and take it down there.
