Now, working in mental health in your area I can translate this for you.. ""She's not really mad, she's just playing up"." Really means, "she has a personality disorder, probably borderline PD which makes her quite difficult to work with. And in all honesty, we simply can't be bothered. (ps, an easy way to get yourself into hospital when you feel you need to be, is to say you think you are Jesus Christ. Easy, inoffensive and bam, there you are in your hospital bed that weeks of suicide attempts and self harm couldn't get you!)
