AQ Flopped Q high

I tried to play higher limits in order to recover from my downswing but lady luck wasn't on my side

PokerStars, $0.25/$0.50 No Limit Hold'em Cash, 6 Players

CO: $50 (100 bb)
BTN: $38.57 (77.1 bb)
SB: $29.52 (59 bb)
BB: $51.79 (103.6 bb)
UTG: $179.24 (358.5 bb)
Hero (MP): $50 (100 bb)

Preflop: Hero is MP with Q A
UTG folds, Hero raises to $1.50, CO folds, BTN calls $1.50, SB calls $1.25, BB folds

Flop: ($5) 4 4 Q (3 players)
SB checks, Hero bets $3.50, BTN folds, SB calls $3.50

Turn: ($12) 2 (2 players)
SB checks, Hero bets $7.50, SB calls $7.50

River: ($27) 6 (2 players)
SB checks, Hero bets $25, SB calls $17.02 and is all-in

I had seen the villain playing very aggressively with KQo flopping Q high in a previous hand

Villain showed Q 6
