Even when i have logical proof that it isn't true I still can't help thinking everyone finds me annoying and hates me.

One example of this is a guy that works in the reception of my accommodation. We get along well, we talk more often than we would need to and often about things that aren't customer-employee related. He'll asks me questions about my family and my life when he doesn't need to. In reality the only interaction we need to have is me collecting parcels or if I have problems with the accommodation, so clearly all other conversation is optional and he wouldn't talk to me if he didn't want to.

 Yet i still can't help but think he hates talking to me and would rather I just leave him alone. And yes there is the possibility that he's just putting up with me for those few minutes. But even then I know this probably isn't true as he suggested I apply for student ambassador next year and he wouldn't do that if he couldn't truly stand me because the role involves working with him for multiple hours. So why despite these solid facts, do I think he can't stand me and how do I stop thinking like this?
