Im normally good at my job, I'm given multiple complicated projects to work on because of my reputation and in appraisals receive praise for my work. However I have had an absolutely shocking two weeks at work since returning from Christmas. I have no idea why but I'm making stupid mistakes completing simple tasks. It's been noticed by the office. I spoke to my manager today and put my hands up and said I apologise, not sure what's happened but acknowledge I've been shit etc (obviously more constructive than that). She basically said she agreed it had been a crap two weeks but knew I always performed above expectation.
Does anyone else have weeks like this? I just can't put my finger on what's gone wrong. I know I'm in for a weekend of work related anxiety about others knowing I've been shit. Just wondered if it's normal to drop the ball sometimes.
