I want to end my life?

You explained your thoughts better than most kids do. I believe your problem stems from low self esteem. Somehow you and thousands of other kids have the idea that you need pier acceptance to be happy. You think looks matters. TV flaunts so-called beautiful girls and gives kids the idea that to be beautiful or sexy is the most important thing. IT IS NOT. Learn to excel at something. Become very good at some art or activity and your inferiority complex will disappear.
