Don't give up. Keep looking for a doctor that wants to help.
I hope you are able to get into a ketamine clinical trial.

I am also trying to get into a trial myself. There is an office about 30 mins from me that offers ketamine infusions, but they want 3k for 6 infusions.

I will be looking into the genetic testing that you mentioned. Thanks for posting about it.
