You reapply next year. I understood the reapplicant success rate was not very good (correct me if I'm wrong), but it's not very useful to talk about reapplicant success rates, since this year's reapplicants are not the same as last year's. In other words, the reapplicants from 2-3 years ago might have been largely poor students overall, whereas this year and last year, people who were eminently qualified were not getting residencies just because it's a tough job market. We'll probably do better next cycle (sorry, class of 2014).
What to do? Everyone seems to be hoping for a preceptorship, either through the AAPPM or one of the non-affiliated ones that crop up. Tonight, the AAPPM will be having a webinar with more information on what they are offering.
Another possibility is to try for an MBA or MPH or anything you could conceivably finish in 1 year, though that's more of a stopgap measure, and it's not clear how it would improve your odds of matching.
