You should never fold preflop when you face a single reraise. If it was capped and you had to call 2 bets, then you can think about folding. But never for one more bet.
The hand might not be over on the turn. Your outs for a pair might be good. Equilab says this about your chances:
Board: 7♦8♣J♦ 6♥
Equity Win Tie
CO 14.68% 14.68% 0.00% { QcTs }
BB 85.32% 85.32% 0.00% { 77+, A9s+, ATo+ }
As you never should have the best hand in this situation, your winning chances all come from outs. 14,7% * 46 is the number of outs you have. That's 6,7 outs, not that bad. You'll need pot odds of 6,5:1 to call that. Unfortunately, you only get 5,2:1 pot odds. But if you hit the straight you will get at least another bet from strong hands, so you have implied odds. That's still not quite 6,5:1 but it is close.
Next thing to look is, can the opponent fold some hands if you raise? You have some equity and the pot isn't small, so the opponent doen't need to fold many hands for this move to be profitable. In fact the move is profitable if the opponent folds as little as 10% of his hands.
The range of the opponent falls into 3 categories: pairs, overcard with gutshot, 2 overcards. It is difficult for these hands to fold. The weakest pair would be 99 which also does have an open ended straight draw. TT has a gutshot and any other pair is top pair or better. I also think he wouldn't fold a gutshot with a overcard. At least not on the turn. After a raise the opponent has 7.2:1 pot odds for a call with implied odds for his gutshot. That's difficult to fold.
Two overcards like AK or AQ are not as strong a draw. Those are 28 card combinations of which 2 are also flush draws. If the opponent folds anything it has to be one of these.
28-2 = 26 candidates that can fold are close to 30% of the opponents range. That's potentially enough but without reads we do not know if the opponent might fold them. One motivation for a call could be that those hands are still ahead against your good draws, like Q9 or K9.
In the end we would like to have a read if the opponet can fold these type of hands. That includes the read if he would bet them at all on the turn. If you have a read like that the opponent reacts weakly to aggression, then a raise should be considered strongly.
Otherwise a fold is in order. But it is close.
