I am very concerned as well. It is important that you nourish your body. Four years ago I didn't eat for ten days and it lead first to mania (the only time that I've been manic) which lead to a psychotic break. The doctors told me that not only can malnutrition lead to physical issues, like organs shutting down but that it can hurt the mind as well. That was my one and only episode of psychosis and I learned the hard way how important nourishing my body and mind is.

Please take care and please consider eating more. Your physical AND mental health depends on it.
