The full measure of January

I'm back at work today. And I don't feel like it, but of course I must. I don't like Monday, I don't like January overall, but the first working Monday of January is even worse. You get the full measure of the month in one go. Now it is a question of getting through the month, one day at a time, one Monday at a time and hope nobody will get me in a foul mood today. Any suggestions on how to get over it, please let me know in the comments section.
