Not doing enough insulin, panic attacks & depression

My brother has been an insulin dependent diabetic since the age of 13 months, he is now 23 years old. Since he was diagnosed my parents managed his diabetes and it was perfect. About 7 years ago he was on a train in India with them and suffered a major hypo (he missed breakfast but had the same insulin dose as normal) after which he refused to take insulin at all. He refused to leave the house, fell into depression and suffers from panic attacks to this day. He is still not taking the correct dosage of insulin to get his readings down to a normal level and has been told he has some kidney damage and ketoacidosis - his dr had told him he needs to take medication for his kidneys for the rest of his life but he will not take these either.

We just can't get through to him to make him understand the damage he is doing to himself. His readings are anywhere between 10 and 20 on a daily basis (this is after about 4 years of keeping them at 20-25) and he won't even take an extra half a unit to begin the process of getting them back down to the normal range for fear of suffering another hypo, he has had panic attacks whenever he has tried in the past so he just doesn't try anymore. We are all so worried about him and just don't know what to do, he refuses to even see a psychologist to help him deal with his experience.

Has anyone been through or know anyone who has been through a similar experience and come out the other side? We just don't know what to do as he won't accept any help from anyone and won't listen to advice or reason. I am trying to find someone who has been through something similar who may be willing to talk to him and help him through this.

Please help if you can, we're desperate to get his diabetes back on track and prevent any more damage to his body.

Thank you for your comments.. The problem is that he knows what insulin dosage he ought to be administering, he just won't do it. He carb counts already (and always eats lots of carbs with every meal) then reduces what he should have by about 3 units so there is no possibility of having a hypo..

I will definitely try and get him to attend a DAFNE course, I think it will help him to be around other diabetics and speak to people dealing with the same condition as him. Thank you so much for the referral.
