Day 2-50% failure

Ok, so yesterday was day number 2 and I started off good. I wanted to go for the left over pizza for breakfast, but I had oatmeal and blueberries instead. (hooray me) I added in some orange crystal light to sweeten it and it was pretty good. I did not eat the egg white I was supposed to at 8, but rather I ate 4 egg whites at 11:30 along with some green beans. Lunch was the same, 1 cup of lettuce with 2oz chicken and 1/2 sweet potato; only this time I added some oil and vinegar to the lettuce. (I just could not choke down dry gross lettuce again.) So up to this point sounds pretty good, right? Well this is where it stops. My husband came to pick me up and we went to get new cell phones and he brought the leftover pizza with him. I ate 3 slices of leftover deep dish pizza on the way to costco. Terrible, but I was hungry since I didn't eat the mid pm snack. We got our new phones and headed home (several hours later). So for dinner we stopped at McDonald's and I had 10 piece chicken nugget meal with large fries, buffalo sauce and ranch dressing. Oh and a m&m mcflurry. Stellar. Already hating this diet.
