Vertigo, panic and nausea

I've was diagnosed with benign positional vertigo several years ago. In fact the tech when I was tested told me I was one of the worst she'd ever seen on the tests. I occasionally get vertigo when falling asleep, I guess my head nods or parts of my brain turn off before they should. I woke up early this morning and while eating breakfast I had a severe bpv episode. Right now I'm ready to puke from the nausea, having a surge of panic from the vertigo feeling, exhausted, and afraid to try to sleep for fear of the vertigo happening,
