HELP MEEEEEEEEEE!

[HomerJay]

I had been a steadily winning poker player for the last couple months. Able to tolerate wins/losses ok, not great. Since I moved up in limits to .50/1 where I am comfortably rolled, I am having a hard time accepting losing sessions. I end up chasing losses by moving up in stakes. I had half my friggin bankroll on the felt a few minutes ago on a stone cold river bluff. After making me sweat bullets, villain folded, but WTF??? I need to stop this. One losing session isn't the end of the friggin world. Matter of time until I chase losses and DON'T win it back. Please help a player resist the temptation to chase losses. Any strategies out there? I know I'm not the only one to fall into this.
