Tips on living with a Bipolar girlfriend who refuses medication...

My girlfriend has recently been diagnosed with Bipolar disorder. We have been trying a proactive approach with conseling and books and internet forums but I am afraid I am at the end of my rope. I just can’t handle the blame for things I’ve not done, the fixation on things that do not matter, the ups and downs, the violent out lashing, the lack of sex, the blank stares, etc. She sometimes drinks to medicate as well and I can’t handle this either. Anyone have any tips on dealing with this? It is driving me crazy.
