Very sad to hear of the sudden death of your husband.
I’ve had the same. Mine died aged 51 after being dumped in A&E with chest pains and no medical assessment in 8 hours. My hubby was sudden too and aged just 51.
Yes, stress can play havoc on bloods, but yours haven’t risen too dramatically. Don’t fret over them. It is a blip as we have so much else to deal with.
Just try to keep the routines that you had before, if you can.
You are aware of higher hba1c and it is important that you do take time for yourself each day.
It’s so hard, I know but you can get back to lowering levels again but now is not the time to beat yourself up about them.
Thinking of you XX
