My roommate is really messy. She constantly throws her things around the room, leaving her items in the middle of the room. Then, she had the nerve to tell me that I do not clean the apartment enough. Why should I have to clean up her things that she leaves around?

In fact, I do not even know where she would want me to put her things away. Instead of me confronting her about my anger, I went behind her back and talked to my best friend about the situation. I was just complaining about my roommate, and one complaint would lead to another, and eventually I was making myself more mad than I was in the beginning of the situation.
