My Biggest Leak

Hey, well tonight I got frustrated and I made a play against a player who looked like a drooler (over the 50 or so hand sample). I had JJ in the sb and this player who was playing a lot of hands raised from middle position. I 3-bet and he called and the flop ran Kxx. I c-bet and the fishy player raised quite large. Now, against a reg I know that this would be a committing raise and as a result Id have instantly mucked. But given the stats I had on this villain, I honestly thought that this could mean absolutely anything, and that a lot of weaker hands than good second pair would call given his previous tendencies, and some of his hands would even fold. So I shipped and he calls with QQ. Now, its quite possible that this player was not as loose as I had pegged him and maybe I should have given more credit on the flop. But as I said I was frustrated and tired of being pushed around and this brings me to the topic of this post.
The thing that makes me tilt the most is when I feel that I am playing well but things are not going my way in the short term; the c-bets do not work, I get 3-bet a ton; No value bets seem to be getting called, we keep getting coolered etc. I seem to adopt the psychology that the players are somehow conspiring against me but this is never ever true! I let it build up and eventually start tilting and end up stacking off light in a situation where it may have been unnecessary - like the example above.
In the short term if it ever appears that we are getting our way less than usual; if things are not working, then it is most likely just a case of a number of specific independent events occurring together and not a drastic change in game conditions.
Until I completely distance myself from the individual results and thus cure this leak I dont think Ill ever reach the level that I want. This is my biggest leak and my biggest challenge so far. I have at least managed to identify the leak; the first step in finding a cure. GL!
