65s turns flush and gets raised

[LowDown22]

Questioning all my plays now in my current downslide. I think I should have been more aggressive somewhere in this hand, but unsure if on turn or river.

Was really considering folding the river there, but just couldn't. I think by not re-raising the turn I really put myself in a tough spot. Or would it have been better to call the turn raise, bet the river and call a possible raise? Any comments appreciated.
