What also helped me a lot is to deactivate notifications of every communication channel ( email, messenger even the phone )
If notifications are turned on, it feels like other people have control over my mental state, because if an incoming email makes a ping it means that the person that just sent me a message caused my focus to shift in the work I am currently doing.
Even if it feels minimal this compounds quite a lot over the course of a day.
I'm currently reading "Stolen Focus: Why You Can't Pay Attention—and How to Think Deeply Again" by Johann Hari and there's an explicit mention of the negative effect on people that immediate notifications bring. Just wanted to mention that it's not only you.
