Patients get a choice of doctors and doctors get a choice of what they want to practice and with whom. We have very long waiting lists here for dermatologists, for example, because they're all doing quick/easy cosmetic botox injections where they can make more money so my husband had to go to a general surgeon to get his possible skin cancer spots removed.

I would go to my primary care doctor and see if you could get a referral from him and/or I'd try other avenues of therapists; social workers, family therapists, etc. It could be there are not that many open spots (signs and lists get old and not updated) and/or others are calling and on the lists, etc. for certain doctors. Many doctors don't take insurance at all, you have to pay out of pocket, etc.
