Your dog definitely had a severe reaction. If your vet can't see you until tomorrow can you take her to an emergency vet or vet hospital tonight?
Here's some info on frontline and what to do in case of a reaction. The only advice offered is to seek veterinary help immediately.

The only possible thing I could think to suggest if you have no option of a vet tonight is benedryl.
Here's a link about the use of benedryl for allergic reactions in dogs.

I want to emphasize that if you go with the benedryl without consulting your vet first, you do so at your own risk. I've never had to use this on any of my dogs and even though I've heard that it's safe, I cannot guarantee how safe it is, or if it will even work.
I would definitely consult a vet before trying benedryl.
The best option is an emergency vet.
Please keep us posted.
