The Vampire Diaries, Season 5

Katherine:
(voice-over) Dear Diary, so here I am alive. Stefan saved me from killing myself. Now he's got me on suicide watch. He says it will be therapeutic for me to write down my feelings about the fact that I'm dying and there's nothing I can do about it. Deep thoughts, mortal coil, blah, blah, blah. Ugh. My hand's tired. (to Stefan) What kind of sentimental idiot writes down everything hey feel? Is this what the prophecy meant when it said that all the Doppelgängers were drawn together like magnets? Because if it is, I any my money back.

Stefan:
I'm just trying to make sure you don't slit your wrists.

Katherine:
Well, this whole neurotic granny vibe doesn't exactly make me want to live. Do you really have nothing better to do than stand there all day and watch me write in cursive?

Stefan:
I'm trying to make sure you don't kill yourself.

Katherine:
And how are you going to do that, you know, since you're still having your little panic attacks?

Stefan:
I'm fine.

Katherine:
Yeah. Of course. You are the picture of mental health, Stefan, after being locked for 3 months in a safe at the bottom of a quarry.

Stefan:
I am dealing with it.

Katherine:
I know. I mean, I heard you "dealing" with it earlier today in the library. It sounded like you freaked out and broke a chair, maybe even two. How are you supposed to help me stay alive if you can't even help yourself?

Stefan:
So does this mean you want to live?

Katherine:
No. It means that I can't work with people who can't give me 100%.
