Sybil (1976) (TV) starring Sally Field or Sybil (2007) (TV) starring Tammy Blanchard?
I think both of these movies have been shown on Lifetime, for sure the newest installment: http://lmn.tv/movies/details.php?id=MOVE+3920
For those in the field of mental health, Sybil's is the most well-known case of the extremely rare Dissociative Identity Disorder (formerly known as Multiple Personality Disorder)--the study of which made and continues to make medical history. I don't know if Sybil was "the first person clinically diagnosed with the disorder". I doubt it. There is the older movie called The Three Faces of Eve starring Joanne Woodward. It's a 1957 American book and film, loosely based on the true story of Chris Costner Sizemore.
