Man that last Chapter hit me hard. Cleaning your room can be a really big thing for people with depression (I think that she has depression, based on her actions and thoughts). It's one of those things that look really strange from the outside. Most people probably think something along the lines of "just get it over with!", but it can be so hard to get up and do even the most basic things. The author probably has experience with depression him-/herselfe or knows someone who does. He/she does a really great job of portraying some common parts of the illness.
