folding winning hand is way more frustrating than a bad beat

[mj2]

this seems like an obvious fold here. you have an early player raising preflop, raising on the flop and betting the turn. you also have a middle player cold calling 2 bets preflop and cold calling 2 bets on the flop with no possible draws. maybe i played it too tight. thoughts?
