I don't like my appearance that I've been hitting myself?

I've been giving myself nasty slaps on my face. My face is red because I am so angry at all this pressure on my appearance. I know looks matter a lot. I feel very imperfect because of my scars, red hair and pectus excavatum. Because people regard these as physical imperfections I feel that I am therefore not very attractive, and that's hard to deal with. I hate people preying on me because of my appearance. They ask 'how come you've got those scars'. What I would like to ask is why God made me this way. Did he want me to fail with women?
