Bi polar with mixed psychotic episodes

So a string of psychotic episodes have occurred throughout my relationship with my g/f. Ranging from accusations of me stealing or moving her things to full blown hallucinating and seeing people around her that were following her. When I say following her I mean people she met 8 yrs ago suddenly appearing on the train or at her work, but they'd changed their name and were pretending they didn't know her. All the time it was a bad thing, she believes the people are trying to harm her in some way. We've been on holiday together and each time these "stangers/people" turn up, it ruins the break for both of us because we're at the mercy of her psychosis. Its now crossing over into our daily routine/life e.g. we'll go to the supermarket and suddenly she laughs and says "they're here again" Its like a real life Hollywood thriller, and scary! God knows how my g/f is feeling. I try so hard to help and talk to her but she's convinced I'm part of it and says to me "why are you lying to me" she asks me to tell her the truth and why is it happening to her. She is now beginning to believe that it all started when we got together and I'm the reason for it all happening to her.
When I try to talk to her about it she starts accusing me of being one of them and trys to start an argument.

Its so hard, I don't know what to do and its wearing me down badly. I've thought about leaving but I don't want to leave her on her own with no help. She's not in a system of support or care but is on quetiappine 600mg after a really bad psychotic episode about 8 months ago. Is this all part of bi polar? or should I be on the 'psychosis' forum?

Hi Cris:

My hunch is she's progressing towards Bipolar 1. Please read the following topics on this forum:

- Bipolar wife kicked me out
- Anger with bipolar spouse
- sleepless in hell

to get a greater understanding and insight in what may be going on.

Listen, I have been there, and it is impossible to get through. You will have to wait until her mind stabilizes otherwise it will be talking to a volcano that will erupt even more violently.

No, I am not suggesting walking away. What I meant by "impossible" is that during the manic bout, it is impossible to communicate with the person, as they are on a completely altered plane from reality. You may talk all you want and it will only antagonize them with the viewpoint you are trying to address. Do remember, to isolate the person from the illness, and that the one you are seeing during the illness is not the one you have known or love. Do what you can to preserve and cherish the memory of the one you knew and loved before the illness took over.
