Vertigo - part of nervous system crash or bppv?

How do you know where it’s coming from?

I’ve had these weird brain crashes in the past that I experienced with a sudden sensory over load like can’t tolerate nothing and my body is reacting to every movement motion or anyone in my room plus a motion spinning feeling while still and laying down etc

This time I experienced room actually spinning like rotating with my eyes going with the room when I woke up 7 weeks ago and ever since I’m left with a spinning motion feeling in my head and in a very very severe state due to nervous system reacting to the vertigo event .

Also have weird pressure squeezing feeling inbetween my eyebrows like the trigeminal nerve branches area that gets worst with any talking , phone use, thinking literally anything .

I can’t tell if this is bppv or it’s coming from the brain when I lay on my left I feel like I’m spinning to my right and if I lay on my right it’s like I’m spinning to my left . There’s no position I feel normal in. Even laying down sitting up there’s some motion there
