this shit hit me last april. scared the shit out of me. at first, i thought it was the flu. i was laying in bed, just woke up, and started to stretch when it hit me. it hit HARD. i couldnt so much as even crawl without falling over, i vomited for a day and a half. day 1 was horrible. day 2 was not much better, day 3, i could get up with much assistance and made it to the dr. holy shit, i was terrified it was a tumor or something. it was without question, the most debilitating thing i have ever experienced. 100% helpless INSTANTLY.
once you find out wtf is going on, it helps so you dont worry, but ya cant help but wonder if it is the new normal or if it will go away. mine went away after about 3 months. then one day, it came back. nowhere near as brutal as the first time, but when it hits me, i freeze and let my brain settle it. the last few days it's been more sensitive than usual, so i certainly feel what you are going through.
there are many videos on youtube that offer suggestions as to physical therapy you can do, and when i did that stuff before, one of them seemed to do the trick. i havent tried them lately because i am functional, and am afraid if i do the wrong thing, it could put me out of commission again for GOD knows how long. i also notice that changing the distance of my visual focus triggers it, not just head movements.
in dealing with this, i've been really surprised at how common it is. more people deal with it than you know. try the youtube videos, and drink a shit ton of water....super hydrate for the weekend. pee until you are tired of peeing. then drink more water...it helps build the fluid in your inner ear and eventually helps the situation...or at least seemed to with me.
