Stress from work bleeding into home life

I had a terrible meeting with my boss today about missed deadlines and I brought that mood home with me. Snapped at my son over nothing, was short with my wife, just generally miserable to be around. The work stress isn't even my fault really but there I was taking it out on the people I love. I need to figure out how to leave this stuff at work but it's hard when you work FROM home. Any tips?
