Day Four here. Help please!! :(

I have been working the program all summer after lapsing for several months in the spring. I was doing really well -- solid with eating, sleep, exercise -- and then I binged on chocolate on Friday.

Back story: I'm across the country from my husband and my dog and my home for two months researching, and I have a sinus infection, and I'm scared about finishing my dissertation in the next two months... all of that started to feel SO overwhelming that I reached for the old bad way of coping Friday afternoon (several chocolate bars from a vending machine). Of course after I felt "better" for about an hour, and then I felt much much worse, so back on the program I went.

Here it is day four (Monday), and I feel like I'm going to explode or collapse. I'm in the library but I can't focus and somehow I've frittered away 90 minutes of precious time already today. I want to go cry in the bathroom but I feel chained to my computer, and yet nothing good is happening here. I want to stick my head in a bowl of ice cream, but luckily there is none around -- it's just the creepycrawly feeling of sugar cravings. I'm supposed to be writing but when I think about my dissertation I want to crawl into a hole.

This is normal right? And it will be better tomorrow? Help! I need hugs from people who have been here, please. :s6( :s7( :s7( :s7(
