Ambra - you asked about the "Magic Mouthwash" - Everyone is different of course but some have a rougher time than others during the Radiation Tx when mouth sores tend to develop and the doctor may prescribe the Magic Mouthwash to help numb the inside of the mouth so that you can eat more comfortably. My son used it off and on and there was also an over-the-counter type that he got at the drugstore that also helped. But whatever goes into your body should always be checked out with your doctor first - even vitamins - as it can affect your treatment. Do try to eat as much as you can now, all your favorite foods - it can really make a difference later in how you feel. I know what you mean about stress affecting your appetite. I was like that at your age, so try to keep busy with other things, to get your mind off all the negative stuff. Maybe you could eat while doing something else like watching TV or lunch with friends or seeing a movie. There are some high calorie drinks that can help, too. You will do great and you will be ok!
