Comfy?

It seems the only way he is comfortable is resting his head on my leg like a pillow! 
Sadly things are not great. The vet thinks it is a tooth abscess and that it will require full on surgery. For now, we give antibiotics and something else, and I have to clean it. It’s relentless, it doesn’t actually stop oozing, and it’s awful, and tonight he was clearly fed up and almost bit me, I was quicker! The collar is supposed to be on 24/7, but he can’t eat or drink with it, so I am spending a lot of time taking the collar on and off. The local vet did not have all the pills, so this afternoon I had to go to Hythe to collect the rest. It seems that vets are suffering like the NHS - two surgeries but only one vet, and no nurse since the last one left. I’m reluctant to leave him, but have to go into work tomorrow and Wednesday.

Why is life so full of worry and anxieties?
