Dramatic monologue backstory

I believe that the main character in this monologue is angry at the doctors for not being able to save her mother. I believe that her mother died of a disease and the girl doesn't want to deal with doctors again. I actually think the girl is in a mental hospital of some sort because she seems to be going crazy, yelling and crying at the people around her. The stress of her mothers death could have sent her over the edge. Some blocking I could use are getting angry and yelling at some points and seeming sad and thoughtful at others.
