Trapped...

To be trapped inside your own mind must put dante's inferno to shame. To grow up in a place that cannot accept the fact that your mind contains to many thoughts for you to sort out must be a new kind of hell.

The main character of Girl Interrupted was not crazy by any means. She was confused. She was trapped inside her own mind with thoughts buzzing about and that did not make her insane, it made her understandably confused. Her headaches, her need to write...sometimes people like her are diagnosed with bipolar disorder or multiple personality disorder because no one can comprehend that they dont know how to sort their thoughts.
She had swarms of thoughts buzzing around in her head and she could not handle them becausee she was so young. It's true that writing helps get those thoughts out in the open, thats why her warden told her to write them down or talk to someone. If her parents had cared enough to listen they would have found that things like talking, writing, finding some sort of an outlet would have served her far better than a mental institution ever would.

Those thoughts that buzz around inside her head could have swallowed her whole. They would have taken over every part of her only to use her body as an avenue to get them out. They say that crazy people say crazy things. I have seen crazy people. Some are dead silent. Others cannot stop talking. Their thoughts have either corrupted their mind to the poing of them retreating into their minds or they have exploded and cannot stop spitting their thoughts out no matter how conveluted those thoughts might be. Nevermind making any sort of sense.

The lead character was not crazy, but her condition was not handled well. She teaches a briliant lesson in the end. She tells viewers, using her actions, that when other people mess up you have the power to make it right. She went to her treatments, she told her story, she found an outlet for her thoughts. She made it better, she made herself better and that is all that matters.
