worst session ever. in a long time

Well this session was short and started off badly and only got worse I feel I started to tilt a bit and now I need to stop and re think my game for awhile....i had recently cashed out part of my bankroll for some expenses and dropped down to 25NL from 100NL when I switched to full tilt poker....I have been a winning player for some time but the last month I cant seem to put any kind of winning streak together. Right now my bankroll is just over $400 and I need to get back onto my winning track...I have my expenses paid for the rest of summer until I go back to school in the fall so I wont be cashing out and I need to start making my way back up the ranks of the poker world because right now I feel like I am just another fish at the bottom of the tank. Here are a few hands from todays god awful session.

Hand 1

This hand occurred when I was already down a few buy ins and I played it way too aggressively and then by the time the board paired I felt committed to the pot, although I was pretty sure he did not have a boat it is still a terribly played hand.


Hand 2

This hand I felt I played fairly well but got unlucky

hand 3

I should have just folded pre flop but then I got my nut flush draw and thought I would play it aggressively.

Hand 4
http://www.pokerhand.org/?1269772

Am i overplaying aces here? I felt he could easily have a ten in his hand but in hindsight the min raise is kind of suspicious and I should have probably folded on the river to his raise.

Hand 5
http://www.pokerhand.org/?1269776

Same villain, same raise, overplaying KK here or do I have to be willing to go broke here...I guess i need to learn my lesson about these min raises by this guy and just respect them but he was playing 85/35 over 50 hands and I could not bring myself to lay these overpairs down.

Any advice on ways to change my play or articles/books I should read are appreciated...I feel like this is the lowest point of my fairly successful poker career....I feel like I have enough bankroll left to salvage this and make my way back up but I need some guidance and some leaks definitely need to be plugged.
