So my personal life just got very interesting. In a net-positive way, certainly, but still, I am, as Calculon put it, "filled with a large number of powerful emotions!" -- some of which are anxious and/or panicky.
This is making it annoyingly difficult to focus at work. I am an absolutely textbook "Attention Deficit Oh-look-a-squirrel!" case at the best of times, and this seems to have made it much, much worse. I can handle small tasks, but anything where I'm going to have to spend an hour solving multiple problems before producing results, I can hardly make myself start.
Has anyone dealt with the problem of maintaining productive focus while emotionally overwhelmed/exhausted, and if so, do you have any pointers?
Net-positive is good! If congratulations are in order, then congratulations!
In my personal experience, the net-positive thrills are terrific, but too few and far between to merit extensive study. If you can arrange to take a bit of a break for a while until your life settles down, then do that. If not, then you probably don't have time right now to do much more than use a combination of common sense and sheer willpower.
The military and the emergency services have a lot of institutional knowledge of how to function during periods of extremely unpleasant stress. For example: http://www.hooah4health.com/mind/combatstress/default.htm .
