That's exciting! I know exactly what you mean about bigger changes being scary. I'm going through something like that right now myself. I think you just have to identify the scary thoughts as the fear talking, and that overall you can do it.
I really admire vet techs. They're working hard on animals who don't want to be worked hard on, and the owners are anxious about the whole thing. Yet, they manage to remain upbeat and friendly and in control of things. They're an impressive group, at least in my exposure to them.
