...advice ?

So I don’t want to Self diagnose, so I’m asking opinions ..? So , for the past about 6 months .. I’ve hated my body.. ive gained 60 pounds in a little over a year. Once I found out my weight .. the number haunts me daily ... so I constantly count calories .. the moment I go to eat one bite of something .. I want to stop, because I feel guilty, ugly , fat, and disgusting... I even attempted to make myself puke ... whenever I eat something .. anything... even if it’s just a serving size ... I hate myself .. I get happy when I don’t eat.. ... so what I am asking is , is this an eating disorder?
