Buffering while working

I am seeing the pattern. While I’m working I feel a feeling in my gut and chest that I find to be very uncomfortable. My thoughts when I’m working are that I don’t know what I’m doing, I don’t know if I’ll do this right. Then I buffer by making tea, or I stare at my computer like I’m frozen. My result today was that I tracked 5 hours of work in 8 hours. I buffered or spun out for 3 hours. One of the coaches said to either work or feel the feeling. I guess I wanted to share that I’m seeing the pattern and ask what I can do to stop buffering when I decided to be working.
