This is totally normal for bipolar people. I do it to my friends all the time. I've done it to guys before too. You may have lost her. Try to get in touch with her again, but not too often. She'll probably not appreciate feeling stalked. Sadly, you may have to expect that you'll never see her again. I know I've said a lot of things to guys that I know have gotten their egos up and then once I'm no longer manic, I can't believe I said the things I did.
