Oh yes. I relate. My normal wt. is about 110# but when really anxious over time I have dropped to the low 90's, that usually gets me focused on eating again. I find grazing helpful, raisins, nuts, hot cereals, yogurt, some fruits, cheese and crackers sometimes...
I seem to actually 'forget' to eat. When reminded, I do not feel hungry.
