If food, the scale, or the protocol starts taking up more room in your head than the rest of your life, that is its own kind of stop signal.

In the US you can reach the National Alliance for Eating Disorders helpline at 1-866-662-1235 (weekdays), or text "ALLIANCE" to 741741 any time. Outside the US, a GP or local crisis line can point you to the right place.
