50NL Trouble with big pairs!

[BYRNE11]

So heres my story...about a year ago i deposited $100 and through bonus's and winning built my bankroll up to about 2500(playing mostly limit) but had to cash out when the whole Neteller thing happened.Ive been a long time lurker of the poker forums and a occasional poster in the sports betting forums. I got my money back online in July on Pokerstars and have been playing full ring NL 50 as much as i can which is not much since ive been working alot before i go back to school,but plan on playing much more in the winter. So far since depositing ive had the normal up and downs but have had alot of trouble playing large pairs which is for most part a major part of the downswings ive been taking part of it is bad luck but most of it i think is ive playing them bad since it seems to be happening way to often. Anyways heres a few hands some winners some losers any help is appreciated.
