Stress Eating

How do people deal with stress eating? Somedays just get to me, I get too overwhelmed.

Today was one of those days, my 2 year old has been sick since Sunday and cries almost constantly. My 13 year old drives me nuts, well because mainly she's 13. I'm also pregnant with my second, my husbands third, child and the anxiety of the situation simply overwhelms me. I try really hard not to give in but sometimes I just can't fight the urge, and do.

What are some good tactics for not turning to the fridge?
