Hey Elle. I too was unofficially waitlisted to the Northwestern program and did not receive my very official rejection letter until the very end of July, so I spent most of my summer, as it pertains to grad school, vacillating between trying to forget and being anxious. The silver lining is that in an attempt to distract myself, I took a really powerful screenwriting workshop and finished a new screenplay that I'm really proud of, which then resulted in the impetus to refocus my energy into applying for the USC program for fall 2017.
It's great you had it in you to reapply to Northwestern, as I too know the feelings surrounding that sense of limbo. I had every intention of doing the same but after emailing Ms. Pritchard and with their new application modality I just found that I didn't have the drive that I felt so strongly this time last year. Perhaps it will boomerang back around in the future but for now my eyes are on USC. Best of luck to you with your applications.
