I hope things are calming down by now, but I just wanted to add one thing to the excellent advice that's already been given.
Make sure you are not compounding the problem by being anxious yourself. She needs you to be calm and matter of fact. She was probably as startled by your reaction to the Doberman's greeting as she was to the dog's behavior. Don't fuss too much when she's acting stressed and when you notice her being calm, praise her and tell her how well she's doing.
You haven't ruined her. Relax. She'll be fine.
