Am I stressed?

I haven’t been in the working mode these past few days. Not the usual workaholic like me. Maybe I’m a bit burnt out. Just this afternoon, the bosses are all out of the office. We all wished to go home too. I have been making the Tax report for almost three days now, before I usually finished it in less than a day. I haven’t started my costing report for January in the time that I should be working on the reports for February. I don’t know what’s wrong me with me. But I know this is not the usual me, there must be something wrong.
