Is this what starvation feels like???????

So pleased with Mondays weigh in I convinced myself that I could live on an apple, an orange, a cucumber and a carrot and 5 liters of water a day......Needless to say I feel like ___________. you can fill in the blank. I think this is what starvation feels like. I cant focus on anything, when I bend over to pray I feel like I am going to collapse. I have a constant headache, I feel like I will throw up at any second, I feel like I was in a car wreck and I am catching the flu all at the same time. This isn't how I want to lose weight. I dint even have the energy to get my housework done and I certainly haven't done any exercise in the past 2 days. THIS ISN'T WORKING!!!! sooooo back to what was working for me 2 weeks ago I was having a yogurt for breakfast and sometimes a piece of fruit, then an apple or some other fruit or a cucumber for lunch, then a huge salad with this crunchy fried flat bread as a topping and olive oil and lemon dressing( they call this fatoush here in UAE) then as a snack in the evening I would have some bran cereal or a weight watchers snack or a piece of fruit or a small piece of dessert if I baked cake or something like that. Along with drinking my water this diet gave me lots of energy to exercise everyday and I was losing 4-5 pounds a week, i felt good unlike whats happening to me right now, so I ordered a fatoush( salad) and I am going to eat that tonight and some bran cereal and tomorrow I will go buy my yogurts and I am going back to what was working for me before I lost my mind. Please don't try what I did this past week and a half it was dumb and desperate and yes I lost 10 pounds but I am feeling horrible now and there is no way I could keep this up. Tomorrow is pizza day for the kids I am going to have my normal Thursday pizza treat and then back to my routine, See you on Monday when we see how this all ends up.
Its not ALL hopeless!!!!
