I have lived on the border of reality, much like you describe, but was unable to maintain control of such a thing, and eventually got caught with a net and put back in the hospital, where I was drugged with almost everything under the sun.

I have bursts of mania here and there, mostly at night robbing me of sleep, but I am keeping the real psychosis away with just my little measly 50mg dose of Seroquel. I know I should go back to the doctor and tell him to up the medication, but I won't do that, because I am trying to hold on to whatever humanity I have left, since even this small dosage numbs the crap out of my emotions.

I was once diagnosed with schizophrenia a long time ago, but it was corrected because they misunderstood that it was my bipolar mania.
