One over indulgent meal or even one day of less than perfect eating habits WILL NOT make or break your healthy lifestyle. As I tell all new members,"Don't look at good health or weight loss with an all or nothing mentality". If the only healthy thing you did for yourself today was drink 8 glasses of water, that's still a step in the right direction.
Don't beat yourself up because you're stress eating. You are in a difficult situation. However, one thing you should consider doing is finding better ways to vent your stress that don't involve food. The next time you feel like running to the frig, consider sitting down and having a cup of tea. Tea is very relaxing and soothing. If you don't want tea, put on your coat and take a walk. walking is not only great cardiovascular exercise, it's a great way to reduce stress too. put on your favorite music.

Take deep breathes. Most people don't realize how some deep breathes can also help reduce stress.
try not to worry, but if you know this weekend is going to be stressful, find better ways to vent that stress. If you think you're going to run to the frig, toss out the junk. out of sigtht. out of mind.
