I have anxiety too. Things like crowds and planning vacations don't really get to me, but financial issues do
I would also say that you should remind yourself that it will all be ok and if it is stressing you out, just cut back the planning and step away from the planning guides and boards. Analogizing to my own triggers, I recently deleted Facebook from my phone. I tend to go on it daily for distraction and entertainment but I found myself feeling really stressed and anxious with all the posts on my feed about the election (which, in my mind, leads to anxiety ridden thoughts about the future of our country and the world, and my kids' economic prospects when they become adults). Also, we are in the market for our first home right now, obviously an enormous economic decision, so with the election it is a one-two punch for my psyche.
So for you, I would remind yourself that any vacation is going to be fun, there is no such thing as perfect, just get your body down there, book any 3 FP's and HAVE FUN. Who cares if you meet A&E?
And most importantly, step away from the boards!
