There have been a couple of comments on this thread that strike me as quite self righteous. No one deserves to lose a leg especially if they have followed medical advice that is decades out of date.
Agree 100%
Many people have things going on in their heads that work colleagues or outside of work friends have no idea about. Might have severe depression problems for example. (was watching 24hrs in A&E last night, one poor student stabbed himself due to the state of his mind, he survived, all his friends said he came across as the most together, level headed relaxed member, and one said he was the person that held the group together, they were all totally shocked (and very supportive) when they realised all was not as it seems with him)
A few years ago when my other health problems meant for months at time, I was just existing, my ONLY form of pleasure was food. I can assure you with 100% certainty that had I been diagnosed with type 2 then, I would have carried on eating normally. My only other alternative would have been to kill myself, as as far as I was concerned, if I cant have this one pleasure, whats the point of existing.
Very hard to understand if you've never been there.
Regarding the woman whose lost a toe, she must know it's because of her diabetes, she will have been told numerous times the risks if she doesn't change her diet, which is why I suspect her mind is in a different place to ours, and until (or if) she gets help in the other areas, sadly I doubt any amount of advice will change her eating. Of course that doesn't mean the op shouldn't try.
