East Coast 20-40, QQ in BB

[RobA]

I've been playing live 20-40, 10 or so hours a week, for about 7 months now, and i'm a loser at it. I started at 2-4 6 years ago, have read all the books, blah,blah, beat everything all the way up through 10-20.

Its 3AM and i've been at the table for 45 minutes or so (was playing 10-20 earlier). I'm in the BB with black QQ, not thinking super clearly cuz its late, I guess. Its 7 handed right now because of walkers. MP (my read is that he's a contributor because he's too loose, and calls too light) raises, Button (knows everyone, a dealer in the past, solid tonight, though i'm not really sure if he's a winner or not) cold-calls, SB folds, I 3-bet, call, call.

Flop 6, 8, 8 (2 clubs)

I bet out, MP calls, Button says "lets see what you got" and raises. I think and think and think and decide what turns out to be a bad decision.

Please comment on what you guys think is right here. I'd espectially appreciate comments on how, if at all, the postioning of these other two players affects the decision.
