it's just a weird angle. I was out with a group of friends last week and they kept reviewing all the pictures for what they called "fat face." It just happens to anyone at a certain angle, or with the lighting from a certain side. *shrugs*
Just delete the pic and forget about it! As someone else said, photos can catch people's faces at weird angles...much like the many awful celebrity pics that end up all over the tabloids. We know those people are gorgeous yet even they take pretty awful pics at times.
At your height/weight you are defiantly skinny, and your face looks very thin in your profile pic so I wouldn't worry about it too much.
