I don't know where to start

[iZack]

My new Partner of 4 months has quite severe mood swings and I think that it might be some sort of Bipolar Disorder, she does have a very stressful job and one day be loving and fun the next day really quiet and another just wants be be on her own.
She say's she don't know why she has these moods and can't or won't explain, when I try to talk about it she say's she doesn't have the answers and that her moods are not fair on me, but I want to be with her and help her.
We have not been with each other for a few weeks to give her space and did not communicate for a week then started texting and then last week had a phone conversation, over an hour but didn't talk about her last bad mood.
She has had a bad previous relationships and has always felt that if someone done something for her this would always be thrown back in her face at a later time, I have told her that the things I do is because I love her and want to do things for her, fix a curtain rail or mend her car
How do I go about discussing the possible Bipolar Disorder as this has never been mentioned.
I really don't know who else to ask and I'm sorry to burden you with our problem.
