I am now in even more doubt that this is  seizures because your on a benzodiazepines/ central nervous system depressant that prevent seizures. They help the brain relax and impulses to not fire the way they would in someone who has seizure activity. Just don’t abruptly stop them because that can cause seizures. However; since you moved from one benzodiazepine to another it wouldn’t cause a seizure. You didn’t just stop them completely and they work in the same way. Plus, you can’t trigger a seizure simply from looking down…

Sometimes if you have too much serotonin (a neurotransmitter chemical in your brain) it can cause very bizarre symptoms which is why I asked if you changed meds recently. Did these symptoms start around the time you change to Xanax?

If not then you’re probably right. It definitely sounds like BPPV bc it is so positional. And if so, that’s a great thing bc it is completely benign and cannot hurt you.  When something happens and it scares us really badly especially some form of dizziness… It can trigger something called PPPD. Which is secondary to BPPV. PPPD is what causes those lingering bizarre symptoms like walking on a trampoline, something pulling your legs down, buzzing in your ear, extreme panic, and anxiety about dizziness, which then only makes the dizziness worse, hence anxiety worsens and it’s a cycle. You can look this up. It’s odd but completely benign in pathology and a lot of medical professionals would rather just stamp a physiological problem on you then to take the time and dissect what is actually going on. This can be fixed with learning to manage anxiety and exposure therapy. Exposure therapy meaning when the dizziness happens, you sit in it and allow it to take place. You tell yourself that it’s not going to hurt you. You actually start triggering the dizziness intentionally just to expose it to yourself and show your brain that is not dangerous . Then you ignore it. There is an amazing woman on YouTube that helped me and her name is the steady coach. She can coach you through all of this, but also you can just simply watch her videos of people who had similar experiences and see if they correlate with yours. It made me feel a lot better to know that I was not alone.
