Did I chicken out with my flush draw on the turn?

[hornsandspurs]

I think I played this hand well up to the turn. When the board paired, I got gun shy. Did I just flat out wuss out, or can an argument be made for calling here?

This is my second post tonight regarding flush draw flops. I am still trying to figure out how to maximize the wins with these hands.
