Session's #7 and #8 and $55,000 $11 rebuy notes

Sorry that i misses a few days if anyone is actually reading this;I just i need to add a site counter so i would know. As of right now my current playing roll is about $23 on Bodog.com/$28 on Fulltilt, and i am busted on Poker Stars right now. I actually had to reload my stars account last night with a $50 Visa gift to go;I used this money to enter the $55,000 rebuy tournament. I have busted out of this tournament three times this week on the bubble. I had three rebuys last night and one add-on,and had 6000 in chips after the first break. I ended up losing to AA vs. KK on a K-7-J flop and A-7 river and turn.
The guy ended beating me with a bigger house;I always tend to think of a reason that i lost a particular hand. And i felt that since i only called his raise pre-flop,I didn't give him credit for having poket aces when they appeared on the board. Had i re-raised him pre-flop i would have been able to put him on Aces on the turn;And these are the kind of mistakes that i have to get away from in order to be a winning player.
Poker is a game of information,and when i just called i didn't get any imformation off of my good holdings.I cannot tell you how many times i have done this;As well as calling off my entire stack early in a tournament with high M. Another problem that i encounter is not making re-raises on the flop when i guy sticks out a probe (small bet) bet.
I have noticed this in my game also;That i am letting peeps of the hook with weak hands after the flop.
