help?

I have been told by other girls and boys that I am.. displeasing to the eye. (to put it nicely). Is it normal to lose all confidence? I know I'm plain but is it that for others to leer? I feel ashamed of myself. How can I a queer, young woman change myself? I can't deal with my skin.. I can always be better. I'm losing sleep. Being in my own body hurts. help me
