Python,

I just sat down at your table when this happened:

Hero ($398.49)
CO ($27.65)
Button ($302.31)
SB ($199)
BB ($169)
UTG ($201.53)

Preflop: Hero is MP with 8, 8. SB posts a blind of $1.
1 fold, Hero raises to $7, 1 fold, Button calls $7, 1 fold, BB calls $5.

Flop: ($22) 6, A, 8 (3 players)
BB checks, Hero bets $15, Button calls $15, BB calls $15.

Turn: ($67) 3 (3 players)
BB checks, Hero bets $50, Button folds, BB calls $147 (All-In), Hero calls $97.

River: ($361) 7 (2 players, 1 all-in)

Final Pot: $361

Results in white below:
BB has Ah Ad (three of a kind, aces).
Hero has 8d 8h (three of a kind, eights).
Outcome: BB wins $361.

I couldn't believe it...played the hand back to my wife on PT to show her and she gasped as well.

To your credit, you didn't go on tilt after the hand, playing good tight poker. Hang in there.
