Hello Darren, welcome to the forum.
I was diagnosed in October 2009 (45 years old). I too had a brief period of fear and panic (it lasted 24hrs!). The day after I returned home after being released from hospital, I immediately got down to sorting myself out. No excuses or reasons why I couldn't do this, that or the other.
Things I did included:
1) Getting myself on a diabetes xpert course. Luckily for me that was available within a month of diagnosis. It gave me the information I needed to understand what I had to do.
2) I was given a meter to test my levels (this seems to be frowned on these days, but believe me, it is very useful).
3) I modified my diet to cut down on carbohydrates. My meter gave me huge hints as to what foods I needed to avoid (granola sent my levels soaring!).
4) I started to walk every day. Initially, fairly slowly and for not so long, but this built up to 1hr per day at a pretty brisk pace.
5) I lost weight. Before diagnosis I probably exceeded 20st at some point. At diagnosis I was just over 18st (I'd lost weight because my insulin resistance was so extreme that I was effectively starving!). Over a couple of years or so, I got down to 14st sustainably (I did hit 13.5st, but that didn't last long!).
The result of all this is that I was healthier and happier than I'd been for a long time. I was medication free as well, which I was quite pleased about (but to get there I did have a period on gliclazide ... which stimulates the pancreas to produce insulin and then metformin ... which helps the body use the insulin it produces more effectively).
More recently, I put some weight back on and my levels started to deteriorate again. However, I am back on the road to my 14st ideal and things are improving for me again. So, it is a lesson that I have to continually relearn!
Anyway, good luck with everything. It need not be all doom and gloom!
Andy 🙂
