Ehhh........ well one I know is probably a bit borderline.... I don't know if they do this exactly, but sometimes I'll be thinking about a person I'll normally like and it's like I start viewing them in a bad light..... I may like you one day, and then suddenly within hours you disgust me. I can talk myself out of this and like you again, though.
Probably paranoid and maybe borderline again:
I do something similar where, out of self-preservation, I constantly watch everything you say, looking for a sign not to trust you and whatnot. I'm looking for danger, so I don't get hurt. It's exhausting being so vigliante and keeping tabs on every fault or the 'suspscious' things a person says.
I hate doing this, I can never trust anyone ever, and sometimes come close to ruining relationships over what could be nothing. Also, it keeps me depressed with them because there is always something to be unhappy about. I think I blow stupid things out of proportion.
What's funny is no one knows I do all this, not even my best friends or my ex noticed, because I can hide it well.
OCPD:
Being overconscientious, scrupulous, and inflexible about matters of morality, ethics, or values
Inability to discard worn-out or worthless objects even when they have no sentimental value (I fix things until they can't be fixed anymore, use stuff down to the nub, hoard things that catch my eye or could have a use unlikely as it may be, pack rat...)
Adopting a miserly spending style toward both self and others; money is viewed as something to be hoarded for future catastrophes
Stubborn and rigid
Lolz, according the DSM, you need at least 4 symptoms to be diagnosed with OCPD, and I just made that. Hahaha. I remember a time in life in which it was 6 (all of which were to considerable degrees) and then the AvPD among other things. I was verrrrry neurotic then. Good times.
