If you notice you’re afraid to be hungry, notice that this is really about fear of feeling the emptiness inside. A once-in-a-while hunger won’t kill you so it isn’t really about food. Allow yourself to be hungry and you will allow yourself to experience the true fear of the emptiness that is underneath.
If you tend to fear fullness, this is about trying to feel worthy because underneath you don’t feel good enough. After all, in this culture of thinness, you are considered more worthy if you can ignore hunger. Allowing yourself to be full will help you sit with the feeling of shame underneath.
