Need some encouragement :,(

Ive had kinda a rough week of some kinda stomach bug or something, but basically I had two days spent entirely in bed with nausea and two days trying to eat more normally. Its just been weird and thrown off my workout schedule...only 3 times this week counting today. Yesterday I decided to make my serious commitments to change a reality and cut out processed foods, soda, booze etc and actually give it a real try, for at least 17 days (also reading the 17 day diet, and while I do not plan to follow it exactly, I am using it for some of the ideas in it and for some guidance and motivation) So I have been sticking to my reduced calorie limit (and not really planning to eat exercise calories...I know there is much debate about this, I am not here for a lecture or a debate with anyone, after spending almost a year on MFP trust me I have read a lot.) But cutting down carbs and processed food has been really tough these past two days, my mood has been TERRIBLE. Seriously. Im like a crazy you-know-what which is unpleasant to those around me. I hope this is kinda a detox phase, that as my body settles into a new way of clean eating I will be able to regulate my mood...anyone with any experience such as this? I have 15 pounds to go....which feels like a mountain to climb, and Im feeling grumpy and discouraged, and as a person known to binge I am just doing my best to avoid that. Would greatly appreciate any encouraging words You guys ROCK!
