As a diabetic, nurse, educator & mom. There are very few things in life we can control. For a person with diabetes food is something that we can control. So yes I think some diabetics become OCD about food it's their one thing in this whole picture that we have control over. Also depending on age, life style etc... If they are retired they may not have anything else in their lives to focus on. So I am less concerned about the patient who grabs ahold of life and charges forward as I am about the ones who see this as a death sentence and be come depressed and feel that life is over. This is a great field to work in and you can make a great difference in someone's life by helping them come to terms with diabetes and how to proceed.
