The Last Best Year.

Jane (Bernadette Peters) has a dizzy spell while at home. As her condition does not improve, she consults a doctor who finds that she is very ill and that she has no family to help her through this very trying time. He enlists the help of a therapist (Mary Tyler Moore) who is very hesitant to become involved in this case due to the loss she suffered as a young child. As her condition deteriorates, Jane learns how to come to terms with her past as does her therapist.
