Long before anorexia came to our house, I refused to fast on Yom Kippur. I understand the idea behind a 24-hour fast: to "cleanse" the mind of its emphasis on the corporeal, and to refocus it for a time on the spiritual.
For me, though, a fast made me think more about my body and its needs, not less. Standing in synagogue, beating my breast, all I could think about was food and hunger.
At 13, the first year I was "allowed" to fast, I became so ill with hunger that sometime during that long afternoon, I ate part of a candy bar I found buried in the sandbox behind our synagogue, and spent the rest of the night throwing up.
Personally, I'm much more able to feel spiritual when I'm well fed, well rested, and centered.
Jews wish one another an easy fast in honor of Yom Kippur. Since I don't fast--and since I hope those of you who are actively dealing with an eating disorder are not fasting either--I will wish you instead a day of contemplation, of connection to yourself and others, and a refocusing on your true appetites, whether they are spiritual, physical, emotional, or creative. Whatever your concept of holiness, I hope you can find some corner of it today.
