I'm in your situation couple times per year, when there's so much to do, that I basically work + sleep only. But imagine that's temporary and you'll get over it (e.g. you'll become better at your job, or make a significant progress with the difficult tasks you're assigned to currently - you name it).

If situation takes longer than you're actually able to manage it - maybe there's something wrong at your work part of life and maybe you should consider change?

Side note: This year I've decided to monitor my life a little bit, so I've decided to create notes at the end of each week ( https://lukaszkups.net/notes/?category=lkweekly ) which summaries all aspects about my professional (technology-oriented) and private (social, free time) life.

After 32 weeks, I can say, that not these notes are helpful by any mean, but the process when I sit down and start thinking about what happened last week (& trying to find suitable words to describe it).

I really recommend trying this by yourself, it might be a little refresh and gaining a new perspective to your life.

Hope you'll find a way to improve your life as well, take care!
