Help me help my friend please

Ok where do I start. My friends partner has type2 a normal reading for him is 230 sugars coupled with high blood pressure of 250/180 impressive figures hu! He is in complete denial he doesn't take any responsibility at all his last doctor he saw was feb when the dr said he had to take tablets for both and statins for his cholesterol, and he hasn't seen a dr since he has got a repeat script, he works abroad, so it does make things difficult a little. He has been diabetic for at least 4 years now. The next bit is all the things that is going on and what she is worried about; memory loss not to bad but enough to be noticed, thinking he has done things when he hasn't mood swings like a child of which I have witnessed also, depression, sleeps a lot, diarrhoea about once a week especially when over indulging, creaked heels, pins and needles in fingers and down the outside of his leg he thought his Mobil was vibrating in his pocket... Lack of concentration not retaining names or conversations, just had, losing things, will lose track of conversations and start talking about random topics, he gets upset over stupid things and agree when things aren't going his was just like a teen. Redness in his face and bloating sweating excessively, out of breath when exerting himself. these are just a few things I am sure there are many more, she is very worried and doesn't know what to do is all this down to the diabetes? Is it all going to get worse. He is 55 years old over weight 17-18 stone I would say, he eats sweets, drinks beer wine and fizzy drinks, juice by the bucket load he eats oversized portions chips and junk when he isn't at home, she does what she can to give him a balance diet food wise mainly veg salads with little carbs plus small little pubs mouthfuls with good fresh fruit nuts and berries to try and curb his sweet tooth, but he washes it all down with coke or beer wine juice what ever is too hand and by the time she has cleaned the table away he will have a ice cream in his hand. He eats at least 500grams of sweets a day 2lts of juice a bottle of coke then the beer or wine on top, he will eat bread as he passed the kitchen just for something to eat prob about half a loaf a day... Plus cakes biscuits, all that he buys as she doesn't buy them any more. Please what does she do to get through to him, is this normal? How long can his body take this? She is so worried that she is going to get a call saying he is really ill,

Sorry forgot to say he has meds but he seems to think he can take them like head ache tabs just when he is feeling really bad then he thinks he will be ok again. Although we all are very worried about him our main consern is his partner. It drives her mad that she doesn't seem to be able to get through to him. Or that he just doesn't care it her we need to help point out what she needs to look out for and to help her understand what is happening I know this post sounds strange and unreal in places but what do we as friends do to help the, both

Ok back off! What back off from my friend that cries buckets when her partner goes away for months on end never knowing if she is going to see him again, back off from my friend that needs support and advise that I can not give her as I don't know much about this subject, we her friends want to help her, she feels alone tired and frustrated, I thought that the whole point of forums like this was for positive advise I put this post on as I thought that maybe others may have experienced similar things, and maybe they could share with us how to help her, we realise for him unless he doesn't want to do anything we can't make him although it was us friends that eventually got him to a dr after she had spent 4 years trying... Now it's up to him we know that but she needs help and the only people to help her is her friends as he is not recognising what it is doing to her, I thought that forums like this was to support people that was finding it hard to cope with their illness and advise their partners families and friends to help them understand what the person with the illness was going through! Obviously I have that wrong back off I am sure and happy as you can write such a sweeping remark that you and your partner have no such issues of being able to come to terms with your illnesses and that you can both communicate with each other for that I am happy for you, but the world isn't always as black and white, it isn't for my friend and don't you think that this is a last resort for us to come here and say such things we have tried reading all the websites but quite honest we have found them a little intimidating maybe the wrong word but over whelming with all the information and not having anyone to explain it to us, we don't have a diabetic nurse sitting here and she has tried to see one to discuss things but she is unable unless she has diabetes. Thank you for the positive notes though to everyone that has a valid positive view but I don't think I will be coming back here for help I will try and found somewhere else or someone else to try and give us some support to support her

And by the way I have my own life and part of that life is that I care about the people I love in my life not just family but friends as well and this is called sharing and supporting my friend I also care about people that I don't know and would help anyone in anyway I can to get help if they needed it this is called humanity I believe

I am sorry that my post has started a forum argument as I have said in other posts we their friends are more concerned about her and supporting her but none of us know that much about diabetes, I am as now looking at other postings manly on other sites I have however asked for this post to be taken down as I do not like conflict and never have I don't think I was judgement to anyone I was just asking what the best way to support my friend was and if anyone could help give advise but it's no use asking for advise without the whole story thank you everyone that has given me some really good advise and the emotions looks very informative so good luck all take care of you and your loved ones and thanks once again
