Hello Ginny
welcome to this forum. I am so very sorry to hear that your husband has been treated so badly, that DN seems less use than a chocolate teapot, in fact I would say there is negligence there, your husband should have been referred for specialist advice years ago, his bg brought under control, what a nightmare situation this is for you all as a family.
I am pleased that you have come to this forum, do try and reduce carbohydrate, you can have substitutes for all the 'gunge' like bread, potatoes, rice, pasta,cereals, they are really nothing but fillers Ginny, they have very little nutritional value, read my story in the Success Story link, you will see what the traditional diabetes diet did to me. Also add flaxseed oil and cinnamon to your diet, do a search on flaxseed oil, you will see it is a really good oil to take, beneficial to heart health and lowering cholesterol. etc He needs to get those bg levels down and eat really, really healthy to give his body the best possible chance of fighting back.
Also it is important to cut out transfats, but its probably a bit much for you to look into that as well so just try and learn about the carbs and how they affect diabetes, I strongly advise you to get hold of the Collins Gem Carb Counting booklet and Dr Charles Clark Diabetes Revolution, its an easy to read book, it will be of interest to both you and your husband, these books are not too expensive at under £10.00.
(You could also get hold of Dr Bernsteins book, but it is a lot more complicated to read so you can leave this until later that is if you ever really want to get stuck into the subject).
Like others here have already said, your husband should check whether he really is a type 2 diabetic, its possible that he has been misdiagnosed in first place.
Anyway just do not give up you guys, there is every chance to be healthier again, another thought here, have you conacted the British Heart Foundation for further support as well, here is a link for you -
http://www.bhf.org.uk/living_with_a_hea ... overy.aspx - only a suggestion because I feel that this is a time for you where you need maximum support, all that is available to you so dont be shy about asking for it.
You say that your husband will not be able to work again. For now dont think that far ahead, it will stress you out too much and you dont need that, neither of you do. At the moment you are both probably still in shock about what happened and on edge all the time worrying that another heart attack is just around the corner, this fear is normal, cancer patients (I was one of those once) worry about this too, it takes some time to change your way of thinking. Maybe his employer can offer alternative jobs or he can retrain, he is not too old for that. There is always hope there but for now concentrate on getting fitter and healthier.
I imagine that you have gloomy days, where you are not as hopeful as on some other days, its important that you talk about your feelings and emotions, so dont bottle anything up, talk to each other, you sound like you are very close, so hopefully you can do that, but also come to the forum and talk things over if you/husband feel low or in need of support, there is always someone here to help and listen, so dont be shy or embarrassed.
Finally, your husband is not working at the moment, are you claiming benefits, maybe he is still receiving his salary, if not then check out whether you are eligible to claim benefits and definitely do apply for DLA, if he is on a reduced salary check if you can get help with the rent/mortgage/council tax too. There are also a couple of charities that may be in your area that can help, some of them giving away brand new clothing and shoes for adults and children, it depends where you live though. You are only claiming what you are entitled to, your husband and you have worked hard, now its time to get something back.
Sorry I rambled on a bit.
All the best to you and family
