I understand you, Terry. I had a heck of a time when Ben and me mother passed...it was hard to think it was important to "watch my food intake" with so much pain and sorrow on my plate. I get it.
I hope you can see that you are doing just fine honey. Just pick up after eating things and keep going. Remember that if you can refocus on food, it can take your mind away from the leukemia. The losing weight part of this is a positive with great rewards that can uplift your mood...perhaps making fighting what you have to fight and treatments etc easier to handle. (it has been proven that attitude and upbeat feelings make the fight easier)
I'm glad you have a friend that will listen but tell him the listening is soooo much more helpful then the donut.
Did you get your fill? I would say, make yourself and your health a priority
