Bulimia...i got caught?

So i have been struggling with bulimia for a couple months. Not super bad like those girls on tv...just every once and awhile. My mom caught me tonight and i am really embarred i guess. Now i cant stand being around her becasue i feel like i am dirty or tainted..like a have done something really really bad. Its super acward to. What should i do. and dont just say "talk it out" ..that never works
