FOUR FLUSH AND TOP PAIR WEAK KICKER ON FLOP

[tylerg]

MY friend watched me play this hand and criticized me...
I dont know exactly the situation but ill give you the basic idea...
HERO has 9J diamonds 2$BB all players had about 75$ in stacks

MP raises to 4 hero calls button calls
12BB
flop came J83 with 2 diamonds
MP raises to 8...hero moves all in....button folds MP calls

turn river give me no help...MP shows AA wins 160$ pot

WHERE DID I GO WRONG...or did i?
