Hey. I don't think I can always tell the difference until in hindsight.
Is it just I am feeling great after a long depression or is it something more?
My friend said waking up and describing oneself as feeling FUUCKING AMAZING is not a normal human response to being happy. That happy people are too busy being happy and doing stuff and living to notice their mood, but I think maybe that is only true for people who don't suffer from mood issues. But I don't really know.

As my hypomanias have been few and far between and don't escalate into too dangerous territory I just enjoy it when I feel good and try not to overthink feeling good. You will know soon enough if it is more than happy. Be safe, but try not to ruin a good mood state by constantly questioning if it is an emotion or a pathology. Best of luck. Take care.
