I Am Too Ashamed To Tell My General Dr. About

I am too ashamed to tell my general dr. about my very embarrassing condition of having been bulimic for the last 21 yrs, and epileptic since age 5. I want to be able to stop the bulimia on my own, but fail every time. Please don't judge me, as I have felt a horrible guilt for this for 22 yrs, and could not handle the judgement. Can you please give me by giving me some proven methods? Thank you and God bless you for giving your time.
