How do I force my girlfriend to address her mental health issues?

Ok so she has bad anxiety and everytime she is with me and I’m driving she’s freaking out and panicking that I’m gonna make a mistake which is extremely dangerous also I haven’t done anything wrong and we have been safe. When she has drove at night she almost hit 2 people, then swerved to avoid them and almost hit a pole. Then when we was driving on the highway she freaked out and had an anxiety attack and drove the car off into the grass cause she was convinced she was going the wrong way on the street which she wasn’t.
