Thanks for sharing this, I felt similar sensations, and stuff, 5 years ago before being diagnosed with Bipolar -II (mild) perhaps using diet pills triggered this at that time of my life and family problems, but one thing I do know is medication and keeping psychiatrist appts. helped diffuse what I was experiencing, which was like going to an electronic store and hearing all the loud display TV's going on at the same time, much noise, once on mood stabilizers the chaos was gone, my mind was free, and things became more relaxed, stable once again
I had balked about treatment, then I realized how much I needed it and how it has helped me.
At the present, my pdoc has gradually reduced my dosage and has observed that I am doing fine, no episodes, yay!
I hope any of you who are reluctant to see a pdoc for their Bipolar disorder, will reconsider and go get treatment, life is too short to be miserable.
I am happy that this forum gives us a means of communicating and sharing our experience, a great support forum, eh?

Please take care now,
DE
