Does anyone here find that exciting things, like an upcoming trip or something else that is generally positive causes a lot of stress to the point where it leads to an episode or severe anxiety that causes you to be way off balance?

I have this to the extreme, but I'd like to know how to manage. I remember one vacation I had was planned a month in advance, and I was so worried about it getting ruined. It became a self-fulfilling prophecy...because the stress and ruminating thoughts that consumed me actually led to a mixed manic episode that completely ruined my trip. Anxiety also affects me to the extreme where I come up with worst-case-scenarios.

Over-excitement is also a big problem for me where I take an idea and run with it....which is how some of my euphoric manias start. I usually end up crashing and come "back to reality".

Do you have issues where excitement over things (or positive stressors) affect your BP symptoms or even lead to an episode?
