Well, I have kept most of my disorders and things secret to my family. Though I am not around my parents anymore and am only around my grandparents.

I guess all I can tell you is to be open and honest with them. If you speak from the heart and tell them everything you know about your condition and how you plan to control it, they should understand. However, it might be best to wait until after you start getting treatment that way you can let them know more information about what you're going through. It's good to be open with your family about the things you're going through and I wish I felt comfortable enough to do that with my family.

Wishing you the best,
