What will you do to earn their trust Kristen?
As a diabetic yourself you have MY trust. However, as a grown woman, a teacher too, perhaps that will require some extra "revelation" on your part possibly???
The biggest problem for ANY of us, in my experience are the PSYCHOLOGY pieces. Guarantee that is a real aspect you might want to literally be a teacher for them...
How can you make a lesson? Will you lead a discussion(s) about the things which worry them? Which frighten you? Ever read/accessed Dr. Polansky's "Diabetes Burnout" book? How about gotten/made a copy of the Behavioral Diabetes Institues Teen Ager cards?
Either one will certainly give you imagery (eg Sugar Fairy, Sugar Police, etc.) with which to begin a discussion-conversation with your younger diabetic peers might provide fruit.
Suspect you will also need to raise "Ground Rules" which may well be a challenge if they get brought into scrutiny by admin.???
Consider the what we say in here stays in here idea. What if a child says they don't really test, or perhaps fake tests or lie about tests... something which is NOT healthy, or could in theory become dangerous to their health. Where do you stand on such issues which are certainly not easy???
For honest discussion what will you offer?
