I suggest finding a better psychiatrist. Just flat out, find a better one. One that will work with you and try to separate the tangled mess of ADHD, anxiety and depression symptoms. A lot of the time anxiety and ADHD blend together so much it's hard to tell the difference, but if the symptoms are there then they're there yknow?

I'm about to get my official eval in a couple weeks or so. I was evaluated as a kid but my mom never took it seriously. As an adult I still have the same issues, my T (can't diagnose or evaluate but understands the symptoms) and i talked about the attention span and impulsivity and fidgetyness and she agreed that I could use further evaluation and possibly medication. I'm nervous to all hell about medication, but I'm willing to try. I'm already on 2 other meds (thyroid + BC) so a third or even a fourth I'd be fine with, if it helped.
G'luck!
