Hello, Becca ! Welcome to Spark People !! Don't worry, you are not alone. Many people experience the exact same thing you do. but you know what ? You can make a healthy change.
Instead of eating when you're stressed, find another way to reduce that stress. How about sitting down and having a nice cup of tea. Slowly drinking tea is not only relaxing, but stress reducing.
Take a walk around the block. Walking is not only great cardiovascular exercise, but it will help you reduce stress.
Take up a hobby. There must be something you really enjoy. knitting, crotcheting, scrap booking, stamp collecting, painting, etc... do something that keeps your mind and fingers busy. When you're busy doing something, you won't think about food because you're having too much fun painting.
