I don't think you sound like you're making excuses. I think you sound very reasonable and self-aware. I'm sorry the conversation didn't go well and that your T is not quite himself right now. I've always tended to just go with my care team's recommendations--you're right, it's not really an argument you're in a position to win, and, anyway, it's not like all docs are quacks and meds are the devil. But I've never had reasons as compelling as yours to disagree.
I guess you'll just have to agree to disagree for while. Sorry this is happening.
