Excuse me, danchip, but my cousin is also bipolar. He frequently jokes that he's nuts/mad/crazy or whatever. He happens to have the same name as Batman's alter-ego and so thinks it's quite funny to use the nickname 'Bats', not the least because he says it's rather appropriate for someone like him. I was shocked when he first told me, but it's one of the ways he stays 'normal' and if it doesn't upset him, then it doesn't upset me.
Bipolar robs you of many things, but as far as I know, a sense of humour isn't one of them.
Back to your question, Crazychick, I'm tempted to go with Telephone. Get a decent lawyer and authorise him/her to access your medical records, which can then be presented in your favour and the hospital probably won't have a leg to stand on.
