Looks like I've hit a rough patch

I had hoped the losing session would be a one-day thing. I was wrong. Completely. I did drop back down to 1/2NL yesterday and I still managed to drop $685.60 at the tables. There are two big hands that I played yesterday that I'd like to discuss:

Hand 1: QQ

Someone raised in early position and I called with queens. Flop comes as the most beautiful flop I have ever seen: Q 4 6. My opponent bets and I call.

Turn comes: T. Not a bad card. At this point I am praying he is holding pocket T's. He bets pot size (over 40 bucks I believe) and once again I call. This was my mistake.

River falls: A. He bets big, I raise all-in, he insta-calls and I know I'm screwed. He shows me KJs for the runner-runner straight. I don't blame him, though, because this all came from my horrible play. Had I re-raised that turn heavily there would have been no way he would have called for his OESD. I messed up and I paid the $200 price.

Hand 2: TT

Once again an early player raises and I call from late position. Flop comes Q T 6. I can live with that flop anyday. My opponent bets, I raise, and he calls.

Turn: K. He bets, I go all-in, he calls.

River: unimportant, because he had KK and I lost another $400 pot.

These flopped sets are killing me. I will not give up, though. This is just giving me more determination to dominate those 1/2NL tables today. If you plan on playing them, watch out! Because I'm feeling goooood today!!!!!
