Does anyone here feel they have the special ability to alter their mood?

Like, maybe you're euthymic, but you start thinking "sad thoughts" and those thoughts trigger a depressive episode. OR you think you're hypo/manic, so you start behaving in a hypo/manic fashion, which in turn causes you to actually become hypo/manic.

Or maybe you just think you're hypo/manic and therefore behave that way because you *expect* to be hypomanic. Same idea with depression.

idk if this makes sense
