Sounds hypomanic. You've been spending more than you should, and your mind is racing, you get upset when your train or trains of thought are interrupted.

And yes, stress can definitely induce episodes! One way or the other. I don't think you're full blown manic. You sound coherent enough to recognize what's going on. Full blown mania usually includes psychotic features, such as grandiose delusions or sometimes disturbing delusions of persecution, and even sometimes hallucinations. Also, people in full blown mania have a greater tendency to do things that really mess up their lives. Like spending all their money, 401K or whatever on some theory that an investment that he/she is convinced will bring a massive amount of reward...or, they gamble it all on one hand of blackjack! They make more irrational decisions, but that can happen in hypomania too. A bad one for me is driving. I'll recognize that I'm in a hypomanic state, or some kind of altered state that includes hypomanic features. I'll be driving down industrial roads at speeds over 100mph. I have enough sense to not speed in residential areas, because I have kids. On the highway i might pass someone at 110mph or more. I'm fortunate to not have caused any accidents...when i drive at high speed the lane I'm in is clear. But I could easily be in jail for reckless endangerment if ever caught. I'm getting better though, with age I think...and getting speeding tickets accompanied by higher insurance rates does help to keep me in check
It doesn't help that I have a pretty fast car either.

You sound really self aware of your symptoms, so try to keep that in mind, self-awareness. Don't judge yourself. I hope that you find balance. Enjoy your vacation!
