stressful when shit doesn't go right.
I think for me, what makes it worse is when you do your diligence, do what is expected of you in good faith, then everyone else ruins it for you by not doing their job.
People refuse to return phone calls, refuse to answer emails, they make you chase them and beg for what they owe you.
I find that as much as it seems likewise, if I go get physical exercise, it helps me calm down a lot. I'll generally go for a walk or something and that clears the cobwebs and visions of choking out the person who most recently failed me.
