Men...gotta love 'em! God forbid they let anything "control" them. Know what I mean...rebellious little boys with attitudes, scared little boys covering it up with attitude, or stubborn little boys who won't budge an inch. What's a wife to do short of losing her mind (or her husband)? They just don't like giving up that "control" for whatever reason. I feel your pain...and you being a nurse that must make it even worse. It's your natural inclination to go "hands on" and give advice and "take control"...Hmmm...there's a thought. Keep in mind I'm just thinking off the top of my head. That's my thing.
I'm no nurse and I'm not one of the more learned posters out here in HealingWell-land but I've had a decent thought or two pop out of my head from time to time. I assuming that it's like having the teacher as your mom. No excuses, no forgetting homework, etc, etc, etc... Poor kid, can't get away with nothin'. And if he tries, boy does he hear about it!! "But it's for your own good!" Yeah, but it sucks NOT to have the freedom to leave school at school. Hard on Mom because she sees it as just loving and wanting the best for her boy. Two very different ways of seeing things.
You really sound like you've taken the reigns and taken "control" from him. With good reason though! But you can't play tug-of-war forever. Unless he's a total moron, he knows everything already that you've "put your foot down" about. You said "we" have an appointment on Monday. Is the doctor examining you too???? Yes, I know what you meant, but if you want him to take control of his Diabetes I think you need to accept that the word "him" is singular and needs to be singular in view of the fact that he's an adult. Darn!!! But I know how you feel.
You can lead a horse to water but you can't make him drink...Again, men. Gotta love 'em!
