Most affordable local doctors willing to prescribe ketamine troches?

I'm going to try to make this as short as I can. I was diagnosed with depression 18 years ago and I've been on ssris ever since. They don't work anymore. On top of that, I became a trauma nurse, which means that, well, I've had a lot of traumatic experiences recently.

Ketamine is obviously strong medicine. My doctor even agrees with me- but, for liability reasons, he won't prescribe it to me off label. I know that you can get a bottle of.5 grams of ketamine for 70 bucks. It makes me sick that grifters immediately moved in to take advantage of the situation by charging people who need relief from their depression so much money that they'll never be able to save any for the future.

I know there are people who do. Does anyone have a recommendation?
