How many people know u purge? Right now only 3 people know I

How many people know u purge? Right now only 3 people know I do and I've been doing it off and on for four years.

Two, my best friend and my fiancé

Nobody knows. I purge by using excessively using laxatives. My doctor suspects something is up though , because I am chronically anemic with no other cause.

Oh my gosh..
