The Breakup Girl (2015)

Claire is the middle sister, both literally and metaphorically. She's 29, she has a stagnant writing career, and her boyfriend dumps her. Her sisters are--reluctantly--there to support her, but she doesn't want their help anyway. Sharon is the older successful sister; she's a wife and mother and sees taking care of her family as her job. Kendra's the youngest sister; she's a struggling artist with a free-spirited outlook on life. The sisters are completely different and don't always get along. But when their father shares life-changing news, they are forced to come together whether they want to or not.
