| I am so sorry you are not getting the support you need from you spouse. I don't know if there is anything you can do to make him understand.
The next time he makes a comment like that you could say, it's because I am a diabetic and I am trying to take care of myself so I can be here to take care of my family.
You might eliminate some of the friction in your relationship by always making sure you have the foods you need just like you try to make sure he has the foods he likes.
I really don't have an answer, just don't let him make you feel bad about yourself. You deserve to have something you like to drink just as much as the rest of the family. Come back any time you need to vent. We understand and many of us have already been through what you are going through. Even if we don't have an answer, it sometimes makes you feel better just to tell someone.
