hello luv.
Well, as you can see, there are a lot of women here who share your frustrations. Lots of us have hit over 300 pounds and a lot of the women here have been real life inspirations to me and I hope for you too. I've been obese since 3.5 years old. I understand that feeling of "Omg, what will I look like when I lose weight?" If it makes you feel better, from your picture you are really pretty and I'm sure as you lose weight you will look even more amazing
You don't have the round face that many of us get when morbidly obese. You have no idea how many times other people have been mistaken as me just because they are a really fat blonde.
You are young like myself so we have the great advantage that our skin will likely shrink with the weightloss. You appear to have really good skin as it is, so you don't have much to worry about there. Keep up the great work!
