What is the first thing I should do after a Florida car accident?

 Well, if you're injured you seek medical treatment. Usually, the first responders come and ask you if you want to go to the hospital, you say yes. If you really don't feel you're injured, you're not obligated to go to the hospital, you may wind up injured a couple days later, so you be very careful of whether or not you seek medical treatment or not. Err on the side of caution.
