Do you ever feel like the ugly one in the family?

Like, I am quite literally the ugliest member of my extended family. I have a facial birthmark, glasses, and a receding hairline. I'm the only one with a severe skin problem, and I have almost no hair. I have 2 sisters and they're both pretty, my mum and dad both have full heads of hair, and I'm the only one with skin problems and a receding hairline. I literally don't know what to do.
