Where are you from may I ask maybe I can help?
I suggest calling your local hospital and ask for list of family DR's taking patients ,also try asking the clinics as often the DR's there have a private practice to so you might luck out there, they have lists sometimes as family Dr is way more likely to agree than a clinic, to me you have to get a local family DR.
I would be glad to try and find a name for you if know is you in Canada USA can't help.
Clinic DR's don't like prescribing grow your own sooner just send you to a place that uses this

which my DR tried then I went back and said I can't afford to buy and need to grow he then agreed.
