Hi, I'm having trouble remembering what movie this scene is from (I was a little kid when I walked into the room where my mom and sister were watching it--all I remember are parts of the scene)

It's at night and in some home. This woman is alone and she's very, very thin (I believe she has short brown hair, but I'm not positive). She is about to eat an apple, but decides not to (she's clearly anorexic), and she ends up passing out and ending up at the hospital (maybe she was driving when she passed out?). I feel like she was some sort of dancer, but once again, I'm not sure.

The movie might have been Magnolia or Requiem for a Dream. Does that scene sound place-able in either of those? Thanks in advance!
