Thank you for sharing your story here at SR and my heart really does go out to you and I am sorry you are hurting (and have been for a long time) Some people in society can be so cruel and thougtless. There are many many important points above and I also truly know that beauty does come from within.
My brother in law is blind in one eye....whe I first met him 20 odd years ago I used to initially notice that his eyes were quite obviously different...he looks like he has a glass eye I guess is the best way to tell you.....well 20 odd years on and I never ever ever even notice it! Infact someone recently asked me hey whats wrong with your BIL?....I had to ask them to explain as I had no clue whatsoever what they were talking about!! He also takes it in his stride and has so much to offer the world that it definately does not hold him back atall.
I hope that you will go for some help regarding your self esteem my friend, it wont be easy but YOU are so worth it.
Kindest Phiz :ghug3
