A Florida man is getting the help he desperately needs … after a video of him getting hit by a car while running through traffic went viral.

As you can see in the video … the unidentified man is hit by a car as he jogs through a busy intersection … but he pops right back up and keeps trotting.

Miami police tell TMZ … the incident happened Monday — and the unidentified man was placed under Florida’s Baker Act, an involuntary temporary mental health hold.

Police told us the man is a military veteran and was “high on some drug.”
