I don't get this at all.
OK lots of people are better at this than me and I am not arguing with them for a heartbeat.
But how can you possibly not resent it. I didn't do anything. I looked after myself. I went running, I ate right, I was in decent shape. It isn't in my family. I was happy, I was living my life, I had a job I was good at and now I am at the very least, far less good at it, I am turning down work I would desperately love to do because I just can't handle it. It is slowly wrecking everything and I did not ask for this in any way.
How can you possibly not resent it. It's hateful.
I don't resent being diagnosed with D at all. I was so ill at diagnosis I was sure it was the big C (again), and that I might not have the strength to beat it this time. Being D meant lifestyle alterations, yes limiting at first, but as you turn your life around and get back to better health, you can again pick up those parts of your life you had to sideline, and I find there is very little I cannot do now that I could not do before.
For me going low carb has been my lifesaver - but it doesn't work for everyone. For me it's been great and this Christmas just gone was my third since diagnosis and was able to join in fully with mince pies, pudding, and cake; using the knowledge that LCHF has endowed me with to ensure I didn't spike unduly, and was back into my normal range within 2 hours (without use of insulin or other meds).
My first Christmas was a dark place having been diagnosed mid-November, and being so ill that every day was a chore.
My second Christmas was testing as I had gone low carb and done well, but trying out some mince pies made me so ill, I vowed at the time 'never again', and indeed found it difficult and upsetting to do the shopping back then, looking at 'forbidden fruits' which I thought I had previously enjoyed.
I started prepping for my third Christmas early, and had experimented with high fat foods taken alongside higher carb foods with great success. Hence this Christmas went great, and we're into the New Year with no after-effects.
D does go hand in hand with depression; nearly everyone I've met/spoken to with D has suffered at some time/degree with it, but it can be beaten and come out the other side with a more positive mental attitude. If you are finding it particularly difficult just now, then badger your Team for help - it IS there but you may need to ASK for it. Also if you have a pre-existing mental health issue, then D on top can cause such stress that your BGs are difficult to control at first. Again, something to work at with your Team, and please DO ask for help on this score.
There are no hopeless situations - only situations that people have become hopeless about.
Above all, look after your body and mind, and it will look after you. We are all different, and D is such a varied condition that we each need to find out what works best for us.
