At the risk of painting myself in a negative light: I drink. I go out with friends, throw back some tasty cocktails/beer/Scotch/wine, and vent about my day/week/whatever.
Depending on my mood, I'll either be one-on-one/two/three with a few close friends and lay it all out, or go out with a larger group and just use the alcohol to take my mind off things.
Healthy? Jury's still out. Effective? Yup.
