How Can I Tell?

I am sitting in the library and I realize I feel something haunting me. I wonder to myself, how can I tell if I feel a certain way? I know what I feel, but sometimes I am not aware of it. I wanted to study Organic chemistry, but my mouse dragged me here. I want to share a short story. Its about a girl who doesn't understand herself. Her traits are too submissive and she doesn't really know how to fix them. She has a few friends, but most of the time she is alone. This girl feels very sad yet excited. This girl feels very powerful yet weak. This girl has so many issues, it seems like she might explode. Some of these issues are made up. Sometimes she tries too hard, she doesn't notice that its not meant to be. Maybe she should just be herself. But it's so hard for her. This girl is weeping so loud that it hurts my ears. I wonder when I will be able to help.
