When I first applied to MFA programs, I didn't get into anything. The next year I did the dance again, got into one, and it was at the bottom of my list: I ended up loving it, and then I applied-received an MA, taught a few years at the university & community college level, and loved that, too. Put together a small list of schools/POIs that I wanted to continue my research at/with, spent a year prepping (still tanked the GREs), and so far have been accepted to one, and wait-listed at another (waiting to hear from 2 more).
Untraditional route to a PhD, but it was mine and I owned it, and couldn't be happier. Seems like very few people have a plan for grad school that works out as planned.
Allow yourself to be bummed for a day or two, and then make a new plan and go for it. It'll hurt for a bit, but then new and more doors will open for you, if you work at it. You won't be the first person to have a crappy application season, and you definitely won't be the first to bounce back afterward.
