Phew...what can I say. I see both sides of the coin and neither deserves to be in pain. It is really difficult for her to live with those thoughts...and just as much for you as you obviously love her.
From my own experience, I can tell you that a person with Bipolar has difficulty in holding on to one feeling to the next. The one moment you are up-beat about something the next you don't want anything to do with it.
Those feelings, however are irrational and do not reflect her true feelings. I don't want to tell you something like "Well, just give her her space when she push you away, she'll come around" because that is unfair to you as it hurts to be pushed away even though in the end the other person truely do love you.
I don't want either of you to lose one another.
Can you approach a eastern doctor or religious person. Maybe work something out to find a alternate way to convince her to take something to help her take the edge off the disorder. Even if it is a herbal remedy (Most if not all western medicine comes from traditional medicine, just much more refined and predictable)
You can allways discuss any issue with me and I will try my best to explain it to you so you can at least better understand where it is coming from.
All of the best
