Hopefully you can get some answers by contacting the practice itself. Let them know you have tried contacting her about your needed referrals but she has not responded. They might at least be able to help you with the names of some therapists in the area to check into.

In the event she doesn't get those referrals to you, do you use insurance for your therapy? If so, you might start with your insurance list? Not a good situation whatever the scenario. I hope you'll be able to find a therapist to continue working with.
