Anyone care to share what they think brought on PPPD?

I really think mine started ( September 2021 ) when a supposedly well trained psych nurse tapered me down from Xanax WAY too fast. I told her I needed to go slower, she didn't listen nor seem to care. Also, I have visited a site called Benzo Buddies, A LOT of stories on there about being taken off cold turkey or tapered too fast from Benzos and Anti-depressants, then developing vestibular disorders. I'm pretty sure my central nervous system got messed up, badly, which in turn, began my PPPD hell.
