Hit my hand and fold when it comes?

Ok I've got a hand for y'all. This is a middle-limit game and it's typical to loose as far as preflop raising; there's been alot of cold calling of pfr's as well.

I'm in BB with Q[img]/images/graemlins/club.gif[/img]4[img]/images/graemlins/club.gif[/img]

Early guy opens with a raise and there are two callers MP and LP.

I call to close the betting.--first is that too loose? I plan on folding all but the best hands or a flush draw.

I check to PFRer he bets; one caller I call.

Turn is another [img]/images/graemlins/club.gif[/img] I check, planning on going for the CR.

It's bet to PFR and the late caller raises. NOW WHAT??

The flop at this point is laying me about 4.5-1. I folded and the PFR folded. I feared both being beaten at this point with the obvious flush on the board in addition to a redraw from the Preflop raiser. So I figured myself to be in a raise/fold situation.
What do you all think about the entire hand and the Turn fold in particular?
