Addiction and Fall

The Heroine Suffers from Depression, Commits Suicide... Abusive Writing, Tear-Jerking, and Loses 10 Pounds Suddenly

She Has Fallen into the Abyss, but No One Has Saved Her from It

I want to read a book similar to "Rescue from Drowning". I pray that the heroine is suffering from depression or autism. She is smiling all over her face, but in fact she has already fallen into the abyss and is waiting for salvation from others.
