Sha'Carri Richardson is finally opening up on her domestic violence arrest ... apologizing to Christian Coleman for her actions, while vowing to get help.
The Olympic gold medalist took to her Instagram page to address her July 27 run-in with cops for the first time publicly ... and in a video, she expressed remorse for her behavior.
