@Kirsten - I think that preparing for a face-to-face meeting after emailing is a good idea; I'll even write out notes/prompts for myself and bring them so that I make sure I remember to say everything I want to.
@Poet_kelly - I can't remember the Dr's exact words, but she talked mostly about wanting to consider an ESA as a last resort only if I had exhausted my other treatment options. She mentioned how difficult it is to work with the school to get a housing accommodation approved (I live on-campus), and implied that the benefits might not be worth the trouble if I did pursue it.
Looking back on our meeting I feel as though she might have thought that I wanted an ESA to be an immediate miracle fix, which is not how I've approached any aspect of my treatment. For the most part the conversation came across as her having already made a decision, rather than us really discussing the pros and cons (My therapist shares notes with her and we had talked a bit about ESAs at our last meeting, so the Dr was aware of my interest before our appt).
@Roxie - Unfortunately due to the way my school's mental health center works, this Dr is the only person I have a prior relationship with so I feel like finding a new psychiatrist wouldn't help. My previous therapists were all interns who rotate out every year, so the person I am currently seeing has only known me for about three weeks, and I don't currently have a Primary doc here or at school. I also that having a recommendation from my psych would have more weight with the school than from another source, considering how long I've been working with her and that she would be readily available for consultation.
I have never asked directly if the Dr considers me disabled or not, but I believe that she does/would if asked. When applying for accommodations my school requires proof of disability/condition, and I was able to have her fill out a recommendation without problem.
I think I will work on an email to state my reasoning more clearly and with information from credible sources. My next scheduled appointment with my Dr is in a month, so I will have plenty of time to work on it. And I'll talk it over some more with my therapist to help make sure that I'm being reasonable when I appeal.
