I can soooo relate to what you wrote. It is so hard to focus sometimes when you have to much else going on upstairs. Try and take a bath if you can ... let the warmth heat you up, and allow yourself this time to just .. think. or not think... but most importantly, try not to stress on the paper. Afterwards, get in some comfy clothes, get some tea (or coffee) and try and focus. I find that once i allow myself some time to focus on whatever my mind is fighting for so much of my attention, it is only afterwards that i can somehow reason with myself to just focus on what needs to be done.
Hope this helps... let us know how it goes.
