Well, I can't begin to count the number of beautiful women I've known who do not think they are beautiful. Usually, when that is the case, there are bigger issues at work.
Accepting themselves is the hardest thing some people will ever do. My advice is to focus each day on one thing that you like about yourself -- be it physical or otherwise. Whenever you find yourself obsessed with something you think is wrong about yourself, or if you find yourself in a general spiral of negativity, just stop thinking about it. Make a decision: I'm not going to think about that right now.
In doing so, you can fundamentally change -- albeit gradually -- how you relate to yourself. You can shift your energies from the negatives to the positives.
Obviously, life's problems don't go away. But by focusing your energies on your positives, you can change your frame of reference. Eventually, once your frame is reclaimed, you will begin to see those issues which truly need your attention. The little things will fall away, and your self-improvements will be based in reality and not on negative thought spirals.
It is this method which got me past a long period of loneliness and regret for lost relationships, and on into the next phase of my life. It's also the same thing which has now led me to transitioning. I know my fundamental strengths, can celebrate them, and realize that there's something big which needs some work.
OK, so maybe "needs some work" understates it a little...
