It's no problem. I know I've DEFINITELY had similar symptoms, though lately when I become manic/mixed, I just become catatonic & unable to function due to the variety of crazy things dancing about in my head. But when I lived in a tense situation with a bunch of acquaintances & action going on, I was simply a firecracker! Left & right stirring up trouble, easy to anger, & easy in general, haha!!
Being really happy could be hypomania. Perhaps the storm is over for now... But still make sure to keep yourself calm & avoid overstimulating yourself with too many obligations, so you don't wind up on the upswing again or fall into a depression by being unable to handle everything at once...
I get randomly obsessed with things myself, but I have OCD, so intrusive thoughts only get worse as my mind starts to derail.
