I ate candy! Feeling guilty and gross?

So I've been committed to Insanity: Aslyum for the past 15 days, half of program! But today I had the worst breakfast PLUS some bad candy. I had two waffles WITH a little sryup. Then my buddy came over and he HAD TO HAVE CANDY! Probably ate one pack of gummi worms (200 cals) Peach rings(not sure in calories) and a couple sour straws. I still feel like crap because that's what this type of candy does to you. But I feel bad I ate something bad, should I feel guilty if I've been clean for 15 days? I've lost all the weight I wanted to, just need a bit more body fat on the stomach. A PART OF ME IS ANGRY AT MYSELF!
