Thanks Hanadr. I appreciate your comments.
I think I'm wasting my time though. I suggested to her she try a new diet this week, which she half heartedly agreed to, but then last night, Monday, she had takeaway and buns in the evening thanks to my sister, who is always eating junk food and giving it to her, and she's off to the town today and to M & S no doubt to buy lots of sugary/bread goodies as per usual.
I only buy healthy foods, lots of salad, meat, fish, brown rice, etc...which she has little interest in and I can't stop her from going shopping and bringing home 'bad' foods.
I'm very reluctant to go a lot of trouble cooking her special meals unless she is not going to respect my efforts by not cheating, etc. She's quite weak willed, as I am sometimes. I take after her.
She has become more and more unsociable since her divorce over 30 years ago, but she does seem keen on joining a crochet class, so I'll try to find one for her.
Your suggestion about accompanying her to her next diabetic nurse appointment was tried before and she got very upset when I mentioned it, so I abandoned the idea. She's obviously hiding the facts from her nurse and is afraid her nurse will find out the truth and I'd embarass her.
It's difficult to try to help someone who has no interest in being helped. I can only try to encourage her. Maybe I can start her on a new diet next week and get through to my sister to stop offering her junk. At the end of the day, though, she is an adult and must by now be aware of the risks involved in continuing the way she is.
