The hand that put me on tilt, (need some advice)

[TheJackal]

Ok, I would first off like to say I've been in a dry spell as far as my cash game play. (my NL tournaments on pstars have netted me a lot in the past 3 months). I started out at $3-6 2 years ago and in the early stages played a weak tight game as I was just learning the ropes. I'm happy to say today I'm more of a tight aggresive player, but I still sometimes play to loose as a result of tilt. This hand will illustrate why I went on tilt and something I need to address if I am ever going to be able to be better than a break even player (well for the year I'm up slightly, but if I played my best at all times, I'd be up a lot more).
Last night, I was playing $4-8 with a kill at my local casino. The game was loose and wild, which I like when I'm not getting consistently drawn out on. Anyways 5 or 6 people were taking flops, so I was being a bit more liberal in my starting hand requirements, but not so much that I was playing any 2 cards (a recipe for diaster). Anyways we get a kill, which raises the limits to 8-16. I look down and see AJ of clubs from mid pos. I get two callers from early position (they were both calling EVERY hand without regard to position). I decide to raise, hoping to build this pot if I hit it I can take down a sizeable pot and my hand is good multiway. I get 5 callers, 1 caller to my immediate left, 1 caller from the cutoff, the original person with the kill, and the 2 EP limpers. The flop comes 963 with two clubs. It goes check, check, now to me, well there is no way I am checking this hand, as I have 9 outs to the nuts, and another 6 to probably the best hand. I bet, and everyone but the person with the kill calls. The turn is the ten of diamonds, I bet once again after it is checked, now I get one EP caller and the guy on my left. The river is the queen of spades, I've completely missed my hand. I bet once again, to have only the person on my left call. He flips over T3 for a pair of threes to take down a $300+ pot. After this I go on tilt and leave down $200. Its funny to think these players actually think they made some great play when all he really did was contribute to a pot that I should win about 2 out of 3 times. I dont want to make this sound like a bad beat story if that is how it coming across, I just told it because I wanted to show the factors for why I go on tilt nearly every session. Its almost to the point where I don't like to play poker because this s--- seems to happen all too frequently. I was just wondering how do you all deal with tilt? If I dont address this problem, I will never be a significant winner.
