    The doctors office told me to go to the emergency room and lie and say I was spitting up blood. I spent the night. The next day I was woken at six in the morning to tell me your team was coming in at seven. Then the team told me later that they couldn't operate on me because the doctor didn't know the anesthesiologist and they weren't gonna be able to do surgery until 3:30 in the afternoon and it took forever to release me. I finally left at four or 5 o'clock with nothing to eat.
