Does the VA only give you access to that one psychiatrist

Yes in my current location I am stuck with this one psychiatrist. She has several psychiatrists working under her, and I always get assigned a new doctor among those people, but before they're allowed to approve the Vyvanse they have to pass it by her first, and she tells them NO even if they were about to approve it. She has been the bane of my existence for 4 years. I even left for 2 years and came back and she's still here and hasn't forgotten her grudge against me.

She's like the doctors you describe, she's decided in her own head that ADHD medications are invariably dangerous and she treats me like I'm a rabid drug-seeker and there's no way I can make it any more clear to her that I've literally never even tried or wanted to try or seek any drugs whatsoever in my entire life. I've literally never drank alcohol, I've never smoked anything, I've never taken a pill that wasn't prescribed to me, I don't even drink caffeine unless I have a rare occasion I really need a nootropic, I use it rarely because the tolerance builds up too quickly. And I even had her call my previous doctor on the phone, the doctor who originally prescribed me Vyvanse 15 years ago on the other side of the country 🤦🏼‍♀️ There is just no getting through to this lady, so my last 4 years of laziness & dread & unproductivity & confusion & worthlessness...I dedicate all that despair to HER.
