How bad am I?

o.k. how bad am I? I ate 5-6 fat free pringles while I was hanging out at the island today. I was there all day long and got burnt even after using some sunscreen. Anyway sitting there I picked up one and it was good.... a few minutes later I ate another and before it was over I had 5 or 6. I know they are fat free but isn't this so bad of me?? Julie
