I have a crazy black housemate. She constantly acts paranoid. She is currently scamming benefit money from the government by claiming she has a back injury issue (she doesn't). She does however have a paranoia problem.

She keeps coming to my house mate and mine's living area talking about people hacking her internet. If you try and console her or make her think logically about what she's saying she starts retreating or getting offended that you don't just blindly believe her.

What do?
