Each cat is different. I've been here 9 months & Ravan is finally starting to get better #'s. Some people get results much quicker & some kitties go into remission.
It takes time ! Patience is a Key word here. It's good to read other posts & look at the spread sheets.In time you will learn more & begin to relax.The more you read the
info here ,the more you learn about diabetes, the easier it will get.
It can be confusing when your vet says one thing & you hear different advice here. It took me a while to understand that the people here really do know more than most vets. They have been dealing with Diabetes for years.
You might want to print out some of the info in the Yellow sticky notes & keep it close where you can refer to it. Some of the slang they use here still has me referring to the sheet
I do Yoga, we do Yoga breathing. Breath in slowly thru your nose & slowly out thru your nose. Do it several times.It does work to help calm down when you feel anxious.
The calmer you are the better for your kitties. They pick up on it when you're stressed out.
Everyone here wants to help. You are not alone with this

It will get easier
