Being in this situation is very discouraging. I was there once and remember the constant anxiety of worrying of when I would get in. There is one thing you should do different from me---have a backup plan. Take the GRE and apply to grad school, have a job lined up, do something so that in case you don't get in this year, you'll be able to have a source of income or have some way to begin beefing up your application. I didn't get accepted anywhere and spent my summer applying for lab jobs and trying to get into a post-bac program. I know this semester sucks because of the uncertainty ahead, but please make sure that you at least have a plan B.
