I agree with others. Your post doesn't necessarily sound like bipolar. If I were you, I'd go with my psychiatrist. If I wasn't content with what he said, I'd seek a second opinion.

That said, it took a long time for me to get my accurate diagnosis, though, partly because I never had obvious hypomania. Check out psycheducation.org I've got bipolar ii but spent several years in essentially a constant mixed state with varying levels of hypomanic and depressive symptoms, so no one saw the cycling. Sometimes bipolar really hides.

I recommend working with your psychiatrist or getting a second opinion.
