Sounds like an anxiety or a panic attack. There must be something about sunset that triggers it.

To me it's height. When we cross the Mississippi river, our anxiety and stress increases as we drive that 250 feet up to the bridge....then panic attack! Light becomes acute...heart thumping...damn near passing out and climbing out of my skull. When I make it to the other sude...I'm shaking, sick, shaking,....

Question...did all this start after taking meds? If I don't take mood stabilizers with the prozac I'm hypomanic in lala land....and more reactive to stress.

Talking to your pdoc and maybe adding stabilizers, tranquilizers, or changing script might help.
