I know the feeling. Last year, I was in the same situation, waiting endlessly for acceptance into anywhere. And the nerve-wracking wait just got worse when I knew that many of my friends were getting acceptances into their top choices or somewhere. In the end, it turned out I was rejected by all the programs that I applied to. I was so ashamed to tell this to my lab-mates, my advisors, my friends and everyone else who knew I applied for grad school. I had been through the shame, the self-doubts, the anger and the frustration but I didn't give up. I hold on to my goals and move on with my other plans. I tried again, and now I'm going to attend graduate school this fall, doing what I wanted to do.
I know this is tough for you but some truths remain. No matter how hard you think it's gonna be the end of your world if you got all rejections, it's not! Attending grad school THIS YEAR cannot be your life-determining event and your only plan. Whether you like it or not, there are so much more you can do before the next application season. You can always try again as long as your don't give up. And you are not alone! I believe there are many people on the forum, including myself, who have been through two or even more rounds of application before getting to where they wanted to be. Key is you have to realize that things don't always work out the way we wanted them to.
Try to let go all the negative thoughts and move on while holding on to your dreams and goals. Things will always work-out eventually. And always get help if you need to. Good luck! =]
