OK, I was trying to laugh you out of it, but I can see this is serious. YOU MUST EAT. Caffeine and candy will increase your sense of panic. Eat something with protein. Scramble an egg, make a cheese sandwich or eat some peanut butter. Either of those takes 5 minutes, max.
All the messes in your life can be cleaned up. You don't have to do it all at once.
It didn't take you a day to accumulate the messes and it will take some time to clean them up. Don't drink, and you can clean them up. You are off to a good start. You are just FINE, whether your house is clean or not. You are making your life better.
Now, again, BREATHE.
