I'm sorry you had to go through that, she sounds like a loonie. Call your car insurance company and report the accident and give them the police report. Just looking at the circumstances they'll be able to tell what happened. Also, take pictures of your car. I'm sure she's got some sort of record with her insurance company for similar things since she really sounds like she's not quite all there. Believe me, the truth comes out when they look at they type of damage done to each car.
Take care!
