Paranoid or otherwise

I swear that this chick in my office is trying to get me fired. I constantly hear her talking about me and trying to move blame from herself to me. There are only 5 people in this 1500 square foot office, surely she realizes I can hear her. I know I'm not perfect, but I'm a nice person who works hard and it sucks that she's got to make my job harder by constantly making me uncomfortable or unhappy. She's smart and a fast learner, she can move up her own without making me look bad. GRRRR.
