If you have an HR department, talk to them about it.
If you can, talk to your supervisor to modify some job duties until you are back to normal.
Understand what is truly expected of you at work, and home.
POWER DOWN! Turn off your notifications. Keep your phone away from you at night. Renegotiate ways for people to communicate with you so that you have some down time.
Take some time to decompress. The biggest excuse I hear when someone is in burnout mode is that they “don’t have time” to get some rest or power down for a week. I always find that interesting, because if they let it go for too long, burnout will stop you in your tracks and you’ll be forced into taking time for caring for yourself. https://www.verywellmind.com/stress-and-burnout-symptoms-and-causes-3144516 https://www2.deloitte.com/us/en/pages/about-deloitte/articles/burnout-survey.html
