listen to this bad one i put on someone

the tables at AP are uber ****ing tight
i noticed that if you raise in early postion, everyong folds. So i started raising with the most herendous hands i could find to get optimal value from them, i got caught with this one.
UTG i have 84off and raise,
folds to the BB who calls after much debate

board 7Q7
he bets i raise blah blah its capped
turn 8
capped
river 8
capped

show down he has (Q7) for 7s full of Qs
and i show (84)for eights full of 7s

i was tilting very bad before this, but this brought me back to level headedness, and put me 1$ in profit after my BB AQ lost to a small blind 72
board 2A947
