I can get dangerously disoriented sometimes with very bad flashing lights. I often end up needing to close my eyes and have someone else lead me out of the place.

But once it got really scary during a fire drill in my college dorm. I got so disoriented that I couldn't find an exit and ended up wandering until I saw someone else go out a door right next to and so followed them.

I don't have it as nearly as bad as you do though, and I'm okay with turn signals.

I'm learning how to use a mobility cane (the type that the blind use) to get around when vision is just too much and I found myself alone.
