You are wesome just the way you are, so no need to put yourself down. Anybody who won't like you because they think you are not attractive enough for them, is seriously missing out on knowing you. That said, I see no reason why you should consider yourself ANY less than anyone in this world, based on your physical appearance. You are too beautiful a human being to think that you are not pretty enough for your own or any standards.
I can identify with you in one way, but I never had the disorder-I just changed a lot since 2008, including the way I present myself to the world. There's some things in the descriptions that match me, but the most unhealthy ones don't. And judging from you theoretically being enneagram 4, the behaviour you present is not surprising. I worked to change a lot about myself since 2008, because since then I've been freer to become just who I want to be, which is who I really am. In the past, I didn't even try to improve myself, as I frankly didn't care enough. It's a long story, but I just felt that I didn't love myself enough to care about my health and image. It's all the opposite now. Throughout all these last few years since 2008, I really became horrorized at my past image, because it symbolically represented my ties with a past of compromise and being tied to what others think of me, rather than who I should have really been (myself.) I was such a nice man, but really didn't love myself enough, which looking back, sometimes makes me sad. I should have cared much more about who I was, because I really deserved it. But I lived for others for the most part, and didn't care at all that much about myself. I am not particularly obsessive, but I really dislike going outside home "looking bad" (which to me means "not looking like myself"), because I have a newfound value that dictates that I should always take care of myself and my image-this is NOT the disorder you are talking about, though, because I don't feel badly about myself, yet I always find ways to improve my image, for it represents the "new" me that should have been since my childhood, but I never let it be until the last few years.
So, always be proud of yourself, and understand that you are a beautiful person, not only in appearance, but just from the way you are inside-which is MUCH more important, as attractiveness is fleeting, and beauty subjective, but a beautiful heart never loses its shining lustre. Be proud of yourself just as you are right now, even if there are things you rather "improve" somehow. I myself am always looking to improve something about myself and my image, but I look the way I want to look, and I like it very much, whether others like it or not.

There's always room for improvement, but the way we are is already sheer awesomeness-no need to feel we don't match up to some artificial standard that IS NOT REAL. Believe you are a beautiful person, and to heck what others think-just be proud about who you really are!
You are a beautiful human being, and you deserve your own love. There's nothing to dislike about yourself, even if you sometimes think that you would rather look differently. Love yourself with all your heart, Ms.
@brennycat-the biggest, most caring, and loving friend we can have should be ourselves, and you are more than worthy of your own love and acceptance.
