What I should do

Maybe I should just take a break.  I am failing miserably at planning meals in advance.  It is like I am having a hard time sticking to it.  It was too late to cook breakfast, so ice cream and cake was the order of the day.  I had plenty of that as well as eating unhealthy foods.  Next week, I have an appointment with my endocrinologist and she always ask me what I ate the day before.  Now I am worried.  Starting today, I will take my food intake more seriously.  I am diabetic and I am not losing weight.
