I would call and ask to set up an appointment. You may feel you've implied or suggested you don't want to stop working with her, but, ethics and all, therapists generally don't 'chase' or pursue clients. I think you maybe have to go to her and ask if she will continue to see you (assuming insurance/fees aren't a problem). Good luck. I know it's wrenching for therapy to apparently come to an abrupt halt like that.
