When I was full blown manic I had very similar delusions. It took a week in the mental health unit, a heavy daily dose of depakote (mood stabilizer), and a heavy dose of resperidal (anti-psychotic) to bring me back to "normal". I would suggest calling a help-line if you have one available, tell the dispatcher exactly what's going on, and follow what ever instructions they give.
This is how I got to the hospital, was diagnosed, and began treatment. It saved my life and might save yours. Hope this helps. Good luck
