Erin,
This is truly upsetting in many ways!!! Have you contacted NAMI? They may be able to help you find counseling in your area. Also, if there is a university nearby or within traveling distance, you might call their psychology department to see if they have a list of therapists who are taking new patients.
I do not think it's ethical to have a therapist deny treatment because of the means of transportation you use. I'm sorry you encountered this.
Peace Erin!!
NAMI
