Actress Mae Whitman shares why it was so hard to get her endometriosis diagnosis and why it's been painful to live with the condition, even costing her acting jobs. She opens up about hospital visits, pain, morphine and why it all left her stressed, anxious and alone. "The concept of not being able to gain an understanding of what your body is going through is the most infuriating and isolating thing," she tells Salon. Whitman is the executive producer of "Below The Belt," a new documentary about endometriosis.
