It sounds like hypomania/mania to me as well. Are you on any medications? Antidepressants can trigger rapid cycling. It does sound like this feeling is quite unexpected.

It's an amazing feeling, for sure. But the impulsivity and the inevitable crash, not so much so.

Don't apologize to us! We understand.

Also, the mania quiz says 54 & up might be severe mania. 85 is way above that; in fact, the highest possible score is 90. Like other posters, I suggest you show this thread to your therapist, as well as the mania quiz and your result.

Hoping for the best.
