i certainly have downers from time to time i wouldnt go as far as depressed (my wife has suffered that most of her adult life), but yes i do get very moody and argumentative more often since diagnosis, and up until a couple of weeks ago I have larely ignored it as much as i could, my tablet taking was haphazard at best and for a few periods of months at a time completely ignored.
If i'm honest I think i can accept the fact now that after 3 years i'm a diabetic (type 2 diagnosed december 2007), but am I happy about it not at all, and i doubt I ever will be.
That being said my 3 years of on/off denial and stubborness has resulted in initial diabetic changes in my eyes, and the odd burning sensation in my feet when i go to bed so like it or not it was time to change. I started my low (ish) carb diet nearly 2 weeks ago and my average level has gone from 13.1 to 7.9, and with effort i can keep my levels around 6 spiking to 8-8.5 which a lot better than the 18's I was getting.
As for doctors, i try and avoid them as much as i can, the initial information that they gave me in hindsight seems to steer you towards foods that are loaded with carbs, no wonder I had a hell of a time controlling my levels at the start.
So no your not alone, and i'm pretty sure there a lot of people feeling the same way, were only human after all and having to think constantly about what your going to eat, what effect it will have on your sugars, remembering your meds, dealing with thier side effects, testing your levels etc etc is going to even try the patience of a saint so it's only natural from time to time you'll hate this disease and feel down, if you start getting to the point where you no longer want to get out of bed or have no enjoyment in anything you do then it would probably help to get some advice.
