This is a hard one. I think you named one thing you like about you , that being you are loving. IMO that beats beauty hands down. I am thinking maybe you could keep a journal of what others say about you that is positive. Also, on days you see something you like about you write it down. It may be they all match and that you have a distorted image of yourself? Then you would have these facts in front of you on paper to back the truth. That may be a lame idea but it may be worth a shot. Do keep in mind models can pick themselves apart too.
