Hi lealea
It must be hard being a parent or relative of a diabetic. I know I am very obstinate and if someone tells me to do something I am likely to do the opposite. You need to be careful with this since even though you care about your boyfriend and mean well, he may perceive your good intentions as nagging. One thing is if blood sugars are uncontrolled, we are likely to be more irritable and feel lousy so can easily take things the wrong way. At the end of the day, even though you care and want your boyfriend to look after himself, I think we need to be ready to deal with our diabetes and in the end the choice is his about what to do. That does not mean you can't do your best but if he is not ready he might not take heed of your advice. It took me 15 years to even start dealing with my diabetes.
Most GPs are rubbish. I try and avoid mine as much as I can. The nurses, dietitians and doctors at the hospital are diabetes specialists unlike the GP. Your boyfriend could go on a course such as DAFNE which is for anyone even if they have been diabetic for years. He could go online as you have and ask for help here or in some other forums like dlife, dailystrength or a yahoo group. I would strongly reccommend DAFNE, it teaches you that you that you are not alone, and you get to meet other diabetics which is so important and so overlooked by doctors.
I think the problem for me was to do with blaming myself for my uncontrolled sugars, and being so scared of highs and complications that I could not even confront it. If a doctor sees a high HBA1C or high results their immediate reaction is to blame you, so you end up blaming yourself as well. If your sugars are high, you stop taking them and feel worse and worse physically and mentally. It starts a downward spiral and it is sad that doctors cannot see the harm they do by blaming us and using terror tactics about amputation and blindness. I am now trying to think of them as just numbers, which need to be acted on but not invested with emotion.
Whatever you decide to do, good luck and keep us updated, and feel free to ask for support.
