Hi there, MrsK13, and welcome.
🙂 I'm sorry to hear that your husband's situation is causing you so much stress.
I don't know what advice I can give you because I don't know the exact details of your situation. My own experience when first diagnosed is this: for the first four or five years I struggled and felt completely overwhelmed by my 'new normal'. My husband gave input and support when I asked for it, but there wasn't really anything he could do to help me come to terms with my diabetes. It was only really when I found this forum that things started to improve...at last I was surrounded by people that 'got' me and understood what I was going thru. It's only then that I was able to gradually start looking after myself.
You say you've tried everything - it's a tough one, if my husband had tried to coax me into better control it would've had the opposite effect and heaped on more pressure...We all want the best for our loved ones - are there things you can do as a family that can coax him into the necessary lifestyle changes and help him feel he's not alone and under pressure to change - like going for a walk every Sunday morning? Or trying out a new activity that would benefit all of you, not just him?
