carinheart,
In times of intense stress I have totally lost my appetite and suffered from nausea too. My heart goes out to you. Be gentle with yourself. Take deep breaths. Do the best you can to keep some food down because it will help your body heal. Stick with bland food, gatorade, tea. Can you call your therapist and mention this turmoil you are in? It sounds like a lot of anxiety... Have you ever considered an anxiety medication? That might be one thought...
