I've realized a pattern that has emerged in my life. When I'm mentally and/or emotionally distressed, I lose my appetite and have generally no desire to eat. During those times, I force myself to eat at least one thing, but otherwise the thought of food disgusts me. In my mind, eating on top of my distress is just wrong. I'm not bulimic or anorexic, and after I have recovered I go back to eating add much as I used to, but during those times...ugh, I can't do it.
