My anxiety is independant of my bipolar, but during hypo/mania paranoid episodes, it goes through the roof and nothing that's been tried or suggested helps in this case. I have to ride it out until it passes, which it eventually does but feels like it takes forever. I take Ativan sometimes and it's mildly helpful at the recommended 1mg dose and a little more effective when I take 2. My doctor knows I sometimes take 2. I wish I could get a serious tranquilizer for when anxiety is out of control. I hope you find something which works, I know how terrible and f'ing awful it can be. (((Hugs)))
