If this is purely vertigo, I empathize. I have fought horrendous problems with vertigo and disorientation in the water, despite the fact that my ears generally equalize very easily. I have done many ascents while convinced I was doing somersaults, and I have ended up on the surface feet-first on multiple occasions after having my mask removed, simply because I didn't know which way was up.
There are methods for coping with midwater disorientation and vertigo. A big one is to avoid rapid head movement. Apparently, this is an issue for instrument pilots, when they are deprived of a visual reference outside the plane. I finally figured out that some of my worst vertigo episodes occurred when ascending in midwater and looking for my buddy/buddies. Now, the people I dive with are told ahead of time, "Stay where I can see you, or you are on your own." I cannot crane around to look at people, or the vertical hold on the world goes out . . . I have also learned a lot of non-visual cues for orientation in the water, including feeling where the bubbles are going on either side of my face, and noting whether my feet are squeezed or "fluffy" (I dive dry). I use the particles in the water a LOT for stability, and if I have a good, solid buddy, I use them, too.
There was a time when I despaired about this, but I have eventually managed to get both technical and cave certifications by learning to work through this issue, so it can be done.
