Hi Kristen,
Welcome to 3FC!
I feel that I can completely relatr to you. In my family I'm the biggest daughter, grandaughter, neice, and cousin. My grandma always nit-picks at my weight and always makes the comment that I should go on a diet. I have an older brother who is fit because he's a marine, an older sister who is a beam pole because she has really high metabolism, and my kid brother is really big into sports so he's muscular. Standing next to them I look like a walking blob lol.
But I love this website and I'm learning to love myself. I wish you happiness and success on this journey. If you ever need someone to listen I'm here and so are many other women going through what we are.
