Two girls meet in school. The film follows their friendship into adulthood. One of them goes into art school and isn't very good at relationships. In the last scene, the artist gets a call from her friend: she's cancelling their girls' night out so she can have sex with a man (her husband?). The artist, feeling lonely, kills herself with some pills she had in the bathroom. I've been looking for this movie for a long time; it must be at least 20 years old! Any ideas? Thanks!
