TO YOU TOO ... I just answered another person in this forum with the same issues ... so many of us go through this, so you are not alone. Why you do this ... take a good look at your daily life right now -- have you had any sudden emotional upsets lately? Have you been feeling down or disappointed? Frustrated, angry, sad, worried, or anxious?
What kinds of foods are you binging on? Do you take a daily vitamin? Are you eating enough? ARe you eating nutrient rich foods?
It is possible your body wants a rest for awhile; try to maintain at least for now (a doctor suggested that). YOu haven't gained anything; so don't panic yet ... ah, that's anxiety & fear & worry of the unknown; of things that have not happened yet ...
You know how to eat healthy; just get back to it. As I said to the other poster ...
You have done very well up until now; so you know how to eat healthy. Getting back on track is a process of steps; one-at-a-time. Take the first one NOW: which is decision; then committment; then action ... plus keep coming back here for support ...
BTW ... the best motivation of all is ... prolonged good health!
EDIT TO ADD: yes, CHLOE ... one snack, one meal, one day at-a-time; even if you make a mistake, keep going ... and get that junk out of your house ...
