Please, by all means, do not allow yourself to become "worked up" about this appt.
There is no need whatsoever to make yourself "nervous" about an upcoming appt. with neurologist.
He/she will most likely (in *most* of our collective NT experience/s here) spend even less time with you than your last GP appt. Yes.
Neurologist will likely only do very rudimentary, ultra-basic, gross neurological checks with you in the exam room; no 'big tests', no MRI, no CT, no EEG --- okay? It's really no big deal.
He/she may or may not write orders for further tests, but truly the neurologist appt is no big deal whatsoever.
Don't let your mind run away with you over this upcoming appointment.
If anything, like most of the rest of us here, you'll be ultra disappointed in the whole experience.
Good luck to you and keep us posted.
