Typical Area of Confusion - suited cards in the SB

[ASaysFull]

Hello all, this is my first post. Getting back into playing, this time I just want to learn. So here is a hand I face often that never seems to work out. Chasing a flush from EP. Should I be out of this hand altogether? What is your strategy with this type of hand...how would you play it differently?

Pre-Flop: Q[img]/images/graemlins/club.gif[/img] 7[img]/images/graemlins/club.gif[/img] dealt to Hero (SB)

Flop: (5 SB) 9[img]/images/graemlins/spade.gif[/img] 5[img]/images/graemlins/club.gif[/img] 3[img]/images/graemlins/club.gif[/img] (5 Players)
