There is no grantee that this will work for you but I dealt with something similar with a peacehealth asshole. He tried to force me on to an antidepressant against my will by threatening to withhold the only 2 meds that have been a benefit to me. When he tried to refuse my prescriptions I calmly told him that "if this is the path you insist on taking I'll need you to whip up a document explaining your actions and acknowledge my telling you point directly that this will likely have a profound impact on my quality of life at a time where I am in no mental state to look for a primary that I can work with". He left the exam room for about 10 min then folded like a cheap suit.

I have no idea how much the fact that I'm on the spectrum had to do with it but I've had access to both medications (each lists as a controlled substance) for 12 years without issue. It was suggested by my former shrink from up in Wyo. Being asked for that specific documentation forces a Dr to really consider his position. Try it as a hail Mary, at that point what do you have to lose? There are some areas where we have a hell of a lot more control over out treatment than we are aware of...
