The yellow wallpaper- what is the form of rebellion?

In the yellow wallpaper the biggest form of rebellion for the wife is a combination of two things. Continuously, the wife secretly writes letters and stories when her husband isn't watching. In this time period, the way that women rebel is by going against tradition or the normal guidelines for what a housewife should be doing.  Throughout the story the wife is getting sick, and looses even more of the ability to do things on her own or take care of herself. She doesn't necessarily want to be taken care of but, she also doesn't have much of a choice. Her way of rebellion is writing, which she can't keep from her husband for long.
