Sorry to hear Calloway's glucose went up. Hopefully they'll get the dose of insulin he needs narrowed down quickly and he'll be feeling better soon.

It's not that hard to give insulin shots. We've had MANY a client come in terrified of needles or giving shots, and a week or two later and they're old pro's at it and say it's not as big of a deal as they thought. You'll get the hang of it quickly, and get over your nervousness after a few times. Usually the vet will have you come in and give the shot there a couple times to make sure you can do it correctly and help if you have any questions.
