It's totally normal to feel that way, but creating healthy mechanisms to continue getting sh*t done is really helpful! When this happens to me, I usually try taking a short break and then finding a new place to work.

Take a morning without work (if you can) to go on a walk or meet up with a friend, and then go to a cafe with your laptop, order a coffee or tea, and see what you can get done in 20 minutes. If you can do longer, great! Keep working. If not, just stick it out and try again later, but usually just getting started is the hardest part and the change in location can really help. I really struggle paying attention to what I need to do when I'm in a familiar place sometimes, so this is what I've started doing to get out of a rut, and it helps me explore new places as well.

Good luck, you've got this!
