20k hands at 100 nl...i still havent figured it out?

[creative]

Rewind to july, i have 3 ft's on ps including a second in the 3+r, i run my bankroll up to just short of 7,500$
until this point i had never topped 2500, i was running well and playing well. I was playing .5/1 and fairing very well, i made around 2700 of the 7,500 playing .5/1 6 max and felt extremely comfortable. I take a 3 week break to travel etc with freinds and hang out before school starts.
Flash forward to school.
I try to get serious about poker and obviously start a big downswing, thats ok, whatever, i know big swings come and go. But the problem is..i cant really find my groove again.

Below are my stats for the first 20k hands on PT and im at a W$SD of 53.5 and im down almost 500..at first most of the problem probably was variance, but now its compiled to bad play and i cant figure out how i can have 53% sd and still be getting my ass kicked.. over my last 7-8k hands ive been winning 59-61% of sd's and STILL losing or breaking even, i dont really know whats going wrong, some people are telling me i must be losing all my big pots and that im probably building some pots with marginal holdindgs or playing to high of variance poker..but is that all it is? is that easly fixable? help me please.. :\
