Hi
@Craigwer,
Sorry to hear of your ordeal. That really sucks, to have such a thing happen to you.
As some have suggested stress can put up one's BSLs, but maybe with a recent diagnosis your pancreas gland is still producing enough insulin to keep levels even.
Certainly seeing your GP or a psychologist/ psychiatrist is a good idea.
PTSD is a complicated condition I gather and only a psychologist or psychiatrist is fully qualified to diagnose it.
Your symptoms are real and yiu deserve all necessary help.
Best Wishes for a steady recovery.
