im not taking my eating disorder seriously?

so I was recently diagnosed with Binge eating disorder and I just can't rake it seriously. like I feel stupid. compared to things like bulimia and anorexia, I just feel so dumb. like I don't deserve to get to day I have an eating disorder because binge is not nearly as serious as those. maybe it just hasn't sunk it. does anyone have some advise? my family doesn't take it very seriously either, so that might be part of the problem.
