Knowing doesn't make it easier

So I’ve had animals since I was 7, and I’ve worked at vets for the past 6 years. You’d think I’d be better about this stuff. Bunny’s having an op tomorrow for an abscess in her dewlap. I can’t stay as I panic if things go wrong. But if I leave I’m frantic with worry. As it is I’m worried sick, despite the fact I know my vet has hardly ever lost an animal under anaesthetic. 🙁 …want bunny well…
