That's what I'd do. Get her private Pdoc help till she gets on the right meds. Then get long prescriptions 90 days with refills.
Good luck. I was lucky. My folks had good insurance and it was decades ago. ( my first episode)
But now Help sucks for everyone. Most people inc me have to pay Pdocs out of pocket. The better ones no longer accept any insurance. It's terrible.
There maybe a sliding scale Pdoc too. Ask.
