Manga with suicide themes or just depressing (if you're on this list, are you ok?)

She kinda just wants to die te whole manhwa. It's an isekai (One of my favorites btw) where FINALLY the FL wants to go back to her own world so she doesnt really care about dying and tries to commit suicide (it doesnt work tho)

Romance with suicide (the whole plot it's that when one of them tries to commit suicide they go into the others body). I rlly liked it but still not finished

This is not rlly depressing but the girl kinda was some problems.. with suicide? You have to read it, i enjoyed it, but not sad
