First and formost, he needs to get his sugars down. That can cause organ failure among other things, until he does this, since that is the reason for your most current issue, you may just have to wait it out. There is nothing that you can do or say other than to help him control his bs levels that are going to make things any easier. I'm sorry that you are having to deal with this, but until he is healthy, your chances are not on the upside. Good Luck.
thank you for your advice really appreciate it =)
