Hey ya Big Ape - Sorry for the downswing. Something that 'might' help you get over it for now; Go to the Tilt forum and read a little bit. You'll see you're not alone dealing with crap like this. It might sound stupid, but it's helped me before.

Also, I just read Elements of Poker and Angelo stresses the importance of being "a good quitter" and he says it's a skill to be learned and one that can be practiced. By that, he means that we should learn to quit playing a session as soon as we notice that we're not at our best. That could be because of tilt, being tired, being hungry, being stuck, not having fun, etc. It's important because most players are not good quitters and they suffer for it. You can practice by taking breaks at a certain predetermined time, regarless of running well or poorly or quitting a session after a predetermined length. The point is to take control and practice quitting. It will help you for years to come.
