I think it’s quiet normal for everyone doing the diet to become emotional in the first month or 2. For me being a chef, and I expect most people feel the same, having the basic enjoyments taken out of your lifestyle is a very depressing issue. The first few weeks were awful and got to a point where I hardly ate anything for a week or 2, just enough to survive and really did hit rock bottom. I was very depressed and moody and had a general feeling of emptiness all over. I think at that point I sorta give up on thinking about ever eating normal food or going for a few beers with my friends but had come to far to give up. I think once I did hit the bottom there was only one way to go and after that slowly I started feeling a bit happier and started to not mind eating the boring bland food and at one stadge got to a point where I was actually enjoying them!
It does get better, but it does take time. Keep your mind as occupied as you can and try not to dwell on the whole situation, it’s hard to think about how bad your feeling when your too busy other things. Distraction is key.
