Soccer,
The neuro is dead wrong when she said "she says that there is no way I have PCS/MTBI because I would no longer have symptoms" There is not valid medical support for such a statement.
I am 12 years since my last head injury. Three NeuroPsych Assessments show that my symptoms are unchanged. Have you had a NeuroPsych Assessment?
You might get some help by contacting the Ontario NeuroTrauma Foundation. They have established sound medical science about prolonged concussion/mTBI issues. Check out
www.onf.org and

Please don't let this get you down.
As luduplo said, ask for a second consult with a neuro.
My best to you.
