I've only had one psychosis. I've had a Times that I was very delusional, but only one psychotic break. And it had a lot of PTSD elements to it so what I was saying was partly true. But I was so out of it I wouldn't have been able to post on here and I wasn't quite sure what was happening.
So I don't know if I'm of any help, but it does sound like you have some insight. Can you try taking some extra zyprexa and contacting your pdoc asap? Try some grounding skills? Lavender really helps to ground me. Other strong, soothing smells as well. Try and use your five senses? I'm sorry, idk if I'm any help at all. So sorry you're struggling.
