Worthless and a screw up. The mistake i made yesterday at work is plaguing me still today, and probably will for the next 14 days. As operations manager at a hotel, those types of mistakes are pretty costly for everyone. It was a tiny simple mistake and i should have remembered to get the info needed. i'm just not thinking as i used to and this is confirming to me that i need to step down n give the position to someone who can do the job as i am useless at it. The same uselessness i am with the people in my life.
I would try to put it out of my head, and to not let it bother me, if I were you. It sounds like it was an honest one that was made, and since that is the case, then whatever happens, happens. It's like in sports where if you fixate on your screw-up's, you will only affect your future/or present performance by dwelling on it, and then also feeling worse about it, as it then inhibits your ability to do as quality or good of work. Or it can/could. If it gets in the way - or you let it. And even if it doesn't, then it will still affect you personally, as it drains your confidence & begins to take a toll on your mental and other kinds of health. If it was a big mistake, or problem for them. I'm sure someone who is your superior will let you know. And they will communicate with you both how much of an error you had made was (in their eyes, the ramifications of, and so on) and also what if any kind of reprimand is necessary and therefore in store for you. Anyway, can't go back in time & fix or change it. So just (best to) let it go... : ) // I mean, it's different if you made a habit (out) of this. Or if you had done so in gross negligence, or on purpose - as in, sabotage, of some kind. But neither one of those seems/or sounds quite correct based on your descprition(s).
