fold this Q high flush??

scenario: party 6 max 50 NL.

my stack - 85, holding Qd Jd on the button

folded to me and i raise 4x BB $2, looking like blind stealing

SB folds BB (a decent player) calls

flop comes 8d 5c Td

SB bets $2, i raise to $6, SB calls

turn comes 2d

SB bets $0.5, i call $0.5

river comes Kh

SB bets $6, I raise to $20, SB goes all in (about same as my stack)


my action? and how did play this hand til the river?
