Is it worth it to see a functional neurologist?

My epilepsy diagnosis was changed to PNES after several normal EEGs. My psychiatrists insist I have epilepsy. My neurologists insist I have anxiety.

My neurologist referred me to a functional neurologist, but it’s $900 for a first visit. 

I’m willing to try anything, but I have a feeling that $900 is going to get me a prescription for yoga to manage my stress…🙄

What have your experiences been?
