Since you asked for suggestions somewhere between stuffing your anger and letting it rip... I don't know as this is the right thing for you to say, but here's something I think is somewhere inbetween... (purple where I reworded slightly)

But my emotional mind feels betrayed, like the hard work I'm doing is being discredited. I want you to help me cope with the symptoms of depression. I want to know why I'm doing all the work of constantly and consistently going out of my comfort zone if you think just some pdoc is what I need. I want to know what good therapy is to me if she believes that medication is the solution. And I want to know what else she wants from me... what more could I possibly be doing aside from becoming magically well??

I don't always think expressing anger at a therapist is something to nurture in ourselves, but it sounds like you usually don't express anger and you really feel it now. So if you can do what the posters above suggested, and talk to your therapist about how you feel really close to being really angry, I think that's a lot better than saying what I wrote. I also think a lot of what you wrote are valid points that one could discuss in a pretty logical, detached way- there isn't anything ethically wrong with asking the questions. I don't know what I'm trying to say. I don't think you should try to excessively suppress your feelings when you talk about this, I'm just hoping it might make you feel more comfortable bringing it up to know that they are good, valid questions that I think anyone should get answers to, whether they are angry or not.
