Losing $1.1k on One Pair Hands

[FourNickel]

I win with all other final hands according to PT except one pair hands over 15k hands, which I have lost $1109. It is obvious I am overplaying/misplaying these hands terribly. I have a hard time differentiating between value betting these hands agianst a lower kicker and getting screwed over by a bigger hand. How do you guys deal with these hands? Play em strong then drop them to any resistance? Please help me plug this horrible leak. I will try to post some hands but any general or sitiuational advice would be greatly appreciated. Some PT stats on One pair. total times: 5617, saw flop: 1736, folded flop 554, folded turn: 256, folded river: 147, went to SD:289, won $ hands: 609, won money at SD: 40%, % of total hands 43. I know 15k is a small sample but I need to stop the bleeding now.
