Is there a single card that could come on the river that would make this worth holding on to? Qd? Td? Other than those, which probably only tie or come in second, I don't think anything else improves your hand.

I kind of like the raise on the turn but from your description of the table it doesn't sound like it will get rid of AK, KQ, or a real flush draw, all of which make you cry.

It might be time to check and see if anyone is watching and quietly switch to a table where you aren't card dead.
