Plan ahead for going out, and even for what you might order. This helps ensure that you’re mentally prepared, as well as appropriately dressed for the occasion. Planning ahead to eat is also a basic skill for feeding yourself well. It allows you to decide on food that will be truly satisfying and enjoyable BEFORE you’re immersed in a stressful situation where decisions can be tough. If something else delicious grabs your fancy once you get there, go for it. But if you’re feeling stressed and worried, go with your backup plan.
