Ever heard of the movie Mommy I dont like it this way or Momma I dont like it this way?

about a woman and her son who lived with this guy that was abusive to her and the boy (forcing the boy to box and beating the boy all the time) it came out between 1977 to 1980 not sure. but anyway this boy is always having visions about this angel and he ends up sleepwalking and gets hit by a car in the end ....
