This day sucks

I lost my f.... AA two times today.
I didn't slow play them. I raised 7x BB preflop, once a guy came with 75o, and the flop was 553, so I was out. Now I raise big also, KQ comes, there's a Q in the flop, she raises, I go all in, she calls, and guess what's the turn. Damn Q. THIS SUCKS. She had 2 outs, and hit it. Aaaargh. And it was the beginning, and easy double up, but a fall out instead.
Sometimes I feel poker is just a stupid gambling game and you can be an addict fast. I'm glad I never deposited. My bro bought 125$ of my yesterday winnings, coz cashout ain't that easy in my country... Well, we will see tomorrow's game, I'll be there for making it to the top4.
