Caught in the Cooler

Severely caught that is. The third hand of my session yesterday went as follows:

Blinds are 0.5/1$, my stack is around $40, and the SB and BB have about the same

All fold round to me on the Button and im holding Qd 10s. I just call. SB raises to $3, BB calls and I call. Flop is Jd 9c 8c. So I've flopped the nut straight. SB raises 5$ and BB calls, i raise to $12. Both call me so the pot is now $45. Turn is Kc. They both check to me, and I raise $20. SB goes all in, BB calls and obviously I call the extra $5 ish. SB turns over Ac 10c for nut flush and BB turns over a set of 8's. River is blank so SB takes a $120 pot.

I keep recalling the hand over in my head, and Im still not sure how I could have avoided losing my stack to this. I maybe should have checked the turn but I thought that maybe the SB had QcQx, which means he would have been on a flush draw.

I played great from then on in though and was up about $70 for the session. Up about $120 so far in three sessions since I started playing again.
