worms of riona

At her uncle's funeral (whom she didn't know), Riona felt truly incapable. Her morals and people's expectations were battling. She should've been sad, but she wasn't. She didn't know what would be adequate of her to do and what wouldn't. She didn't know how to comfort her mother and she didn't know how to react to the stranger's eyes glazing over her.
After the funeral, her mind seems to have turned against her. Her soul and body seem to no longer have the same purpose, that of keeping Riona safe. Her mind seems to want to crush her soul. But is it really so? Did her mind not just truly face reality for the first time and is it not just trying it's best to keep Riona safe, in spite of it's crippling, constant fears?
