I appreciate this post. With multiple rejections in hand, I think we're in the same boat (and subfields). Having spent the past three years consciously preparing for this (MA, great GPA, stuff for the CV, building relationships with Profs, strong LORs, tailoring my application to schools, getting feedback on my SOP, etc.) the prospect of having to go through the application cycle and all of its time commitment, stress, and uncertainty yet again is frankly exhausting. Doubly so since, as you said, it's difficult to get a sense of why the rejections keep coming -- in this difficult environment, it all feels a bit random, quite frankly. I think at least a couple years out to re-evaluate is needed. Each year applying to schools feels like a year where, due to the uncertainty of where you'll be in a year's time, you're putting your life and career on hold.
