Slip ups

I've been having some trouble sticking with the diet. I have couple of very good days and then I have a huge craving (no matter how much fruits I've eaten before) and I can't resist it. It's so annoying and I can't believe how easy it is to go back to those old patterns. I don't know what to do about it. Usually it happens when I'm upset, bored, annoyed, angry or otherwise emotional. I believe it's a way to stuff my negative feelings so that I don't have to handle them, I just go and eat my comfey-foods... And afterwards I feel even worse. But why do I keep doing it over and over again, even though I know I feel horrible, especially emotionally? Why was giving up alcohol, cigarettes, chocolate, coffee, tee so much easier? Should I give myself some more time and not be so hard on myself? It's just that now I'm eating all the foods I would have never eaten before while I was eating very clean but not all raw or vegan. Like pizza, chips, bread, and so on. It's so weird! It's as if I'm saying goodbye to those foods and having my last bite of them. I don't know, I'm just feeling sad for not to eat them ever again. I know I'm too hard on myself and don't give myself enough credit. I should reward myself with something nice instead of eating the crap. I found this device which makes noodles out of zucchini, I'm going to buy that for myself to make the most wonderful raw noodles, and I also want to buy me some kettle bells, I love to train with them. I was actually thinking of participating to a kettle bell competition they arrange here in Finland :)
