I guess I keep pushing through the fear, til something happens, then I do a clean up and repeat the process.
The fear of what will happen is often a massive exaggeration of what actually happens. I've done little experiments to 'reality test' in these situations and found that anxiety amplifies fears way beyond what is realistic or even possible.
I remind myself of this in moments where I'm aware that irrational fears have hijacked my brain.
On another note, I've decided to pull back on my workload, not a great financial decision, but a fantastic one for my health, we only live once...Carpe diem.
