Oops!... I Did It Again

I went 4-bets on the turn drawing dead.

40/80 4-handed. UTG limps, button raises, I call with pockets 7's in the SB, BB calls, UTG calls. Flop comes TT6. Checked to the button who bets, I check-raise since the button shouldn't have any of that crap. BB calls, UTG calls. Crap, I don't like my hand anymore. Wow, 7 on the turn, I just check-raised myself into a monster, or so I thought. I bet, BB raises, UTG calls, I 3-bet, BB 4-bets, UTG calls. River is a Q. I bet, BB calls, UTG raises! Damn, really? QT? I call, BB calls. UTG has pocket tens for flopped quads, BB had pocket sixes for flopped full houses. Later I found out the button had AJ. Damn 7 on the turn. I could have easily folded the turn if that 7 doesn't come.
