AArrrgggghhhhh!!!!!!?

Since exactly a month ago, I've lost 8lbs. I didn't really need to lose any weight but I've gone from 7st 13lbs to 7st 5lbs. If your wondering I'm a 16 year old 5ft 2inch girl. But today, I've had a doughnut and about 5 slices of thin crust cheese pizza. I feel reeaalllyy bad about it. Should I feel bad?
