Well on the advice of Mr V Bond (who pointed out taking a break's important) I took a break. The accounts are still not done.. but they're REALLY NEARLY THERE and I'll deliver them tomorrow morning.
Yesterday afternoon as my boyfriend and I had an afternoon followed by a morning off we went away with the tent. It was beautiful - and we relaxed! We spent the night in a pretty mountain area within 10 mins drive of the seaside. There was a restaurant by the sea where I had the days catch of mackerel for tea and boyf had a salmon fishcake salad thing. We just headed back to the tent after that but found there were too many midges to sit outside. Instead we played cards in the tent and had an early night.
So now I feel much more able to face my responsibilities - back on track.
