Ughh. I lost over 150 today on PP.

What could it possibly be about my play that makes people call my big re-raises with the low pair only to backdoor a flush or a full house? Why does my reraise to 30 with AA get re-raised with K5o to all in only for me to lose the hand? Why do people play their pocket 4's to the river when I make a bluff at a pot? And why the hell does my ace high flush on the flop with a 8 dollar bet (16xBB) get called by someone with a set only for them to backdoor a FH??

I am now back to my initial buy-in with online poker, and I am quite sure that I am going to cashout for good. It seems like I am a fish magnet. Are B+M casinos the same way at the 1/2 NL100 tables? Are there any other online sites with much less fish?
