Since I was a teen girl (am 45 now) I've sporatically experienced what I can only describe as a bipolar chemical surge in my brain that lasts about one minute. It ocurs very randomly and rarely. I may have two occurrences in a year, I may go 2 years without any. Many years since my first occurrence I became clinically depressed and have sufffered from depression for about 15 years.
The episode begins with a "good" feeling....a smell or a thought explodes from the ordinary slight smile into debilitating euphoria! I can almost feel a wave of chemicals splashing over my brain as it intensifies and I can make it more intense by focusing more deeply on it. It's like the combination of the pleasure of an orgasm with a feling of extreme happiness and bliss. It is so intense if I'm driving or something similar I try to pull over. The euphoric feeling lasts about 30 seconds followed immediately and overwhelmingly by a feeling of doom and extreme sadness. The sadness is deep and dark unlike anything I've ever experienced just as the euphoric feeling that preceeds it is more wonderful than anything anywhere ever! The doom is also accompanied by a feeling of a wave of chemicals surging over my brain. It then lessens it's grip on me after 30-60 seconds but the sadness lingers sometimes for about 30 minutes after the episode continually lessening in intensity.
Is this like anyone anywhere has ever heard of or experienced? I've gotten "the look" from enough doctors and friends over the years to stop asking.
