FIND WEBTOOM

There’s this webtoon that I remember reading but can’t remember the name. I think it a blue hair female character who reincarnates. And for some reason she’s super depressed and suicidal. Her family is worried about her, and the female character has guilt over for taking over the original person’s body. I pretty sure she tries killing herself by falling off a tower. It was a historical romance I think. Lmk if you have any suggestions that might be it, thanks :)
