Recent hand 4/8 hold em

[Pauliman]

a recent hand at 4/8 hold em at foxwoods. I am BB holding 22, MP opens with a bet, 2 callers, button raises, i call. flop comes 9 2 4 rainbow, i check, all check to raiser, he bets, i call (rainbow board) one more caller and a folder. 3 players in turn card is 4, made my boat and i am thrilled, i check, MP checks, button bets, i raise MP calls 2 bets, button re-raises, i cap it, MP folds. river cards comes 4, i am sick to stomach, i check to button and he checks, showdown my boat 444 over my 22, button shows AA and i proceed to lose a made hand. tough break but i felt i played it well, any thoughts?
