Live grind session turns into a trainwreck

WARNING: If you don't want to hear me whine like a little girl, stop reading. Don't like bad beat stories? Move along...nothing to read here.

Went to my closest casino, River Spirit. They have 4 tables of $1/$2 NL running, none of them are full. They put me at a table that has 2 open seats. I sit down, and immediately 2 players leave, so we're 5-handed.

NOTE: I bought in short for $100.

In my first hand, I'm UTG w/A9hh, and raise to $8. MP and CO call, everyone else folds. Flop A94ss. I lead for $16. MP folds, CO min-raises to $35. I shove for $74 , CO calls. CO has AJo. Turn 3h. River Jc. FML

I rebuy for $100, and run my stack up to $165 when this next hand comes up.

Table has filled up, and after a bunch of limpers, I'm on the button with KJo and raise to $12. BB calls, MP calls. Flop QT5hh. Checks to me, I bet $15 (pricing in my draw). BB min-raises to $30, MP folds, I call. Turn 9c. BB bets $30. I raise to $75. BB thinks for about 4 seconds and announces he's all in. I insta-call. BB has 9To. River Td. FML

I rebuy for $100, and run my stack up to $265 when this next hand comes up.

A reg UTG+1 raises to $10 pre, I'm on the button with 77 and call. I look at his stack...looked like he had a stack of $175 to 180. He should have at least $200 to make this call, but it's close enough. Flop J74r, bingo. UTG+1 bets $15. I pause briefly and raise to $35. He calls. Turn Ks. He checks. I bet $55. He shoves, I call. He has KK. FML.

Turns out I had him covered by $56 (meaning he had $209 to start the hand after all--he must have been holding some chips in his hand I didn't see) and I immediately cashed out and went home.

The first two were no big deal, shrugged it off, kept playing my A game. Can't decide if I should have gotten away from my set on the third one. I tend to think not. He could easily have AK/AA. Not going to worry about it too much.

My decision to quit was to prevent tilt should a 4th bad beat occur. It will be much easier to return to the game tomorrow, fresh and confident, than if I were to take another beat for a bunch of money. My stop loss is 3 BI's, and while I didn't lose that much, if I bought back in and lost again, I'd be over the limit, so I quit. The game will still be there tomorrow. And so will I.
