Okay i need help

I remember this story that i read before about Jessica leaving snsd and falling into depression.

When she sleeps, she wakes up with nightmare hence not being able to sleep. She keeps herself awake by making herself busy.

I remember in one of the chapter is her going back to sm to terminate her contract, she tried calling krystal but she didnt answer the phone so jessica went to the training room to see her but then all sm artist is there and when she leaves yoona catches up with her and try to talk to her but jessica address her as ms Im.

i rmb having her collapse in the story as well and ot9 meet in the hospital.
