New Diagnosis of Small Fiber Neuropathy

I just found out I have small fiber neuropathy. in some areas, it's already severe. Which now explains why I have pots/dysautonomia and my tingling and burning hands and feet, and probably explains my GI problems. it's surreal.. no one found much up until now aside from pots and a brain MRI with a couple of abnormal (but not immediately threatening) findings, but it was all elusive. Has anyone else felt almost in disbelief after getting a new diagnosis? to finally start getting some answers? it's also validating. I'm so used to being dismissed, or things just coming back normal or vague, that I keep getting these thoughts like what if the results were mixed up or mistaken? logically I know it's probably not though. although I still need to find what's causing the sfn now and some other stuff I'm dealing with, it's nice to have found another piece to the puzzle..
