There's no point in thinking about living with 15 rejections until you actually have 15 rejections. I know it's easier said than done, but I'm trying to stay positive till the last minute. There's nothing I can do to make results come any faster, but I can do something about my attitude. I'll be sad if I need to be sad, but there's no point in selling myself short so early.
BUT! If you don't get in to anything this year, I'd wait a few more years before re-applying. I'm sure you know this, but with the economy in the toilet, applications for graduate school are way up. If the economy turns around in the next few years, maybe things won't be as quite as competitive as far as admissions.
