Not well at all today. I am very tired and and suffering with brain fog. I had to drive to Peterborough for my Performance Plan annual review. My line manager gave quite a reasonable review, for which I was grateful, although my opinion was that my performance had been terrible this year; I had the first days off ill for 14 years and had forgotten loads of stuff throughout the year. Although AF and medication are a serious mitigating factor. Decided not to travel to head office for Thursdays meeting.
