Sorry to hear about the bad beats. If you have your hand history, you can post that info and we could give you our two cents. Bad beats happen to all of us, I almost put my fist through my monitor last night.
Anything can happen in the short term. The key is to play a strategy that pays over your poker life. And in the long run, those kinds of cards will pay off.
Anyway, good luck to you, study up, maybe you can give it another shot some other time.
