I fear mania, because once when I was truly manic (with psychosis) due to being on a high dose of steroids and being mistreated my my GP, I had to be hospitalized. Being out of touch with reality was truly terrifying for me.
My hypomania is rarely delightful. It is often dysphoric/mixed. :-P I don't like feeling "crazy," so I take a Bee Pollen supplement to even that stuff out.
When my hypomania IS delightful, I want to stay in it as long as I can. I sometimes feel tempted to drink a little more caffeine, hoping to make it last longer (it doesn't usually last long because I'm pretty stable on meds).
Your definition of stability sounds like my definition of "mild depression."

That doesn't sound very comfortable. I get mild depression on and off and I feel the "stuck" feeling you mentioned. My mild depression often is accompanied by anxiety and obsessive thoughts. What helps me is my NAC supplement (3,000 mg a day) and high doses of caffeine. Mine seems to come and go monthly with hormones.
No idea if that helps, but I just thought I'd give you my perspective.
