A brief description of Rey’s mental state at the end. She thought she was worthless because her parents abandoned her. But since that isn’t true anymore, she still thinks she is worthless because of how much evil her bloodline has caused. This means she thinks she has to prove herself all the more.

So this is a reference to the interpretation of Rey’s core belief?

Also, when can I expect for you to post the version of Rey’s parents being bad people who thought she was worthless?
