Helen Louise,
I just came across your post, and it is kind of akin to my new one ' Good days - not so good days?'
http://www.diabetes.co.uk/diabetes-forum/viewtopic.php?f=25&t=28462. Although I do not profess to be as down as you seem to be. I know many kind people have been writing to you and that you are finding cold comfort right now. Having not seen your original post I am not sure of quite where you are at diabetically - I see that you say you have been fairly recently diagnosed, and I assume you diabetes if T2.
I can only say that when I was diagnosed I was devastated and sat and cried like a baby when my GP told me, I just did not even consider diabetes as neither of my parents had it and I did not fit into the 'at risk' category. I felt like I had been handed a life sentence - both parents lived into late 80s and were comparatively fit up until very late years - so assumed I would be too! However, it does appear further down the line genetically and my brother was diagnosed shortly after me.
It really does get better, there are good and bad days to be sure, and you will never stop wanting it to go away and I know that, like me, you know there are people with far more to deal with than diabetes, or with diabetes and suffering so much more, but sometimes that knowledge just does not help. However, as someone else mentioned, if you are really depressed about it then I do advise you seek further help - I am sure your GP would be happy to assist, one of the questions I am regularly asked by diabetic nurse is 'Do I get depressed?', fortunately I can say 'no', most of the time, but I recognise that it is easy to let it get to you.
I do wish you well, and please remember that the people on this site are all in a similar boat, mostly happy for you to share your distress, moans and all that go with it, very supportive and I really do not know that I would cope so well without them. Sometimes I do not come on here so often, other times I would like to ask some questions and also share experiences, plus today, when I felt a bit more than overwhelmed by this wretched thing :x . But please do keep posting and reading replies, and I do hope that eventually things will improve hugs to you.
