I am going through exactly the same issue, Aviza. My pdoc is insistent about me being on meds, some of them rather high doses, and I keep insisting that I cannot live with that feeling of being "flat". I feel like she's medicating my very personality, the very essence of who I am. And I am feeling extremely resentful.
I spent my last therapy session talking with my therapist about this problem. My therapist was very understanding and offered to sit in on my next pdoc appointment so, as she put it, I "have someone on my side". I was tremendously appreciative, but I told her I'll give it one more try (one more pdoc appointment) and see if pdoc & I can come to some peace with the issue.
I am an artist and I think I know just how you feel. The most absurd part of the whole thing is that it's anxiety that bothers me the most, but I have never found a single medication that truly help with anxiety.
I'm feeling, sometimes, like I just want to stop taking meds altogether, I'm so angry about all of it.
