15 pounds seems too much too long :(

Hi guys! I'm 5 feet 2.5 inches. I have PCOS (poly cystic ovarian syndrome). I weigh 140 pounds now and my goal is to become 125 pounds. All I can think about all day is how fat I am and that i need to loose weight. I can't even concentrate on studying at college. I wanted to know who else was out there in my range. Weight is easy to loose when you have support from others. My friends want to lose weight but they don't want to sign up here. I am looking for friends who can support me and I will support them back :)
