Kelly, Why not just call her back and say everything is fine now, maybe just a case of nerves.
It sounds like you're doing fine, just relax and try not to freak out, there's enough money in this
that they won't cancel unless there's really something wrong.
One thing to remember, on a carbohydrate restricted diet, your blood sugar can get low and cause
shakiness, sweating and overall nervousness. A piece of bread or a glass of juice should
take care of that. Whatever you do, don't call your nutritionist when you're in that state. She
sounds like a bit of a bully, and you need to talk to her in a calm, collected manner.
Good luck and I hope it all goes well.
