Yes it sounds like hypo/mania . You seem to be racing towards an all out event. And, yes, it's an incredible ride. I miss being manic a great deal (I am jealous of your rural life). But, I give that up and take my meds, see a psychiatrist, do CBT daily. It is the cost of being stable. i just can't afford to be manic again - literally and figuratively.

A big sign you should seek some help is that your significant other has suggested it. This is a really hard thing to do; so, it seems to me that your current state is having impact upon her and others' lives.
