I Was Committed to a Mental Hospital for Writing a Book

There are one or two things that don't match up (maybe I missed it). The author's speed is very good, but there are a few questions that I don't understand. Is the novel in the book written by the protagonist? Is there a heroine? If so, is Ye Ling the heroine? If not or not, just think I'm farting. I feel pretty good, I hope it won't break down later

If one day I become mentally ill, and those ghosts that were originally hidden in the dark come into the light, I don't know what my world will look like, and whether those who love me and the people I love will leave me. If there really is such a day, I hope I can become a person like Yu Ge, who can always give myself happiness no matter what, live a straightforward life, even if it is raining heavily, I still have to hold an umbrella for myself...

Everyone is paying attention to whether there is a female protagonist, so I will also pay attention to whether there is a female protagonist.
