I had the worst ever day at work yesterday. Things went wrong; we made a mistake, which was my responsibility, and I ended up offering my resignation. It wasn't accepted, but I've spent yesterday and today putting myself through hell.
I feel that I really only have the thinnest layer protecting me from blows: I take things like this intensely personally and excoriate myself for everything I didn't do or should have done. I have hardly slept, I can't eat, I feel completely devastated by what has happened. I realise that it's an emotional reaction akin to the way I feel if things go wrong in my personal life, and this may not be appropriate for work: for one thing mistakes do happen, and if I can't cope with that, perhaps I shouldn't be in that job. But one of the things that makes me good at my job is that I care about the business, and care about the people I work with, and it makes it very difficult for me to cope with disasters like yesterday. I lack perspective and forget how lucky I am.
I know the measure of the individual is the way he or she reacts to things going wrong, and I just have to grit my teeth and get through this. It feels pretty damn hard right now, though.
