I would just bet double on fourth. Check-raising is fun, but it gives your hand away. Bet sixth. There are a lot of hands that seat 1 can have that aren't flush draws. You're playing scared, which is no doubt contributing to your downswing. I think the river bet is close, as it's quite possible that both of your opponents are drawing to flushes and may not be able to make payoff hands, but on balance I like the bet.
