I found out earlier in the week that my girlfriend has bipolar disorder, I realised today that it's much more serious that I had previously thought it was after she had a relapse and was admitted to hospital. The problem is that yesterday she said something awful about her father (which caused a lot of trouble), which was untrue. She's not a liar, she just believes so strongly that what she said is true.
My problem is what to do if something like this happens again, am I supposed to be sympathetic and believe (or at least pretend) to believe what she says, or am I supposed to tell her what I really think, which is that she's delusional. I know that the latter will be likely to upset her, and she'll refuse to admit it. The problem is also that in future, how am I supposed to know whether she is telling the truth? I suppose if she is in a manic state, it might be a giveaway, but to be honest; yesterday I didn't even notice that she was in a manic state.
I really don't know anything about bipolar disorder, if anybody can offer any helpful advice or if you have any links to interesting articles etc. I'd greatly appreciate it.
Thanks.
