Today a boy said i was out of shape

Amelia

Today a kid in my pe class called me out of shape. I'm 5"2 and 110 pounds. Being called fat and ugly in previous years and suffering from self harm issues i took this to heart and was extremely hurt by this comment. But being strong i tried to confront him but he just smiled at me and laughed at me. None of my friends came to aid me and that hurts me deeply. How do i handle this situation.
