My sister is the same age as me, but we're build differently. I'm about 5'5 and weigh 108. My sis is about 5'7 and weighs 120-130. She's convinced she's fat- but she's NOT, she's gorgeous! What can I do to help her understand she isn't even near fat? She always compares herself to others and it makes me so sad to see her making herself feel bad about herself...
