Aside from word choice and whether a certain line should have eight syllables or ten, the actual writing part of being a poet is fairly low stress. You set aside a few hours a day, find a quiet, comfortable place to write, and get to it.
The stress comes from acquiring enough money on the side to be able to afford setting aside a few hours a day, finding a quiet, comfortable place to write, and getting to it.

If you're working constantly to pay bills, you'll be stressed that you don't have time to write. Seems you could find yourself in a real pickle.
