I blacked out (I think) and crashed into someone

I was driving to work like normal, that morning i felt pretty good. Did my morning routine, washed my face, made a shake, and headed off to work. I remember pulling out of the driveway, taking two right turns and then from there my memory is blank. I apparently ran a red light while going straight in an intersection where my GPS has me take a right (essentially, I was supposed to take a right at the intersection I got hit at but because I was unconscious my vehicle continued to go forward)

I then collided with a car while unconscious and did not wake back up until the firefighters came and got me out of my vehicle, I was pretty dazed and couldn’t tell them what the correct date was.

I should mention that I do not have the insurance package that covers bodily damage (I live in Florida) and I have had one case where I passed out on the ground for a few seconds after over-exerting myself by running laps around a track (not while driving) and the cardiologist deemed as a case of dehydration when intensely working out, and that I can continue doing intense activity as long as I am properly hydrated (I was the day of the collision)

I’m not sure how I can prove a sudden medical emergency claim but it’s what happened to me.

What should I do if they sue?
