In addition to the many other great advice that is being shared, I will add one more thing. Anxiety and worrying are very normal experiences for most people regarding the application process. You are not alone. As much as we want to act like it's not there, it is. It does have the potential to be unhealthy, but it can be chanelled into other arenas. During this period of waiting, I challenge you to find a hobby, read a few books, hit the gym, set a short term goal, ect. Do something to preoccupy yourself while you wait. The only catch is to have a short term goal attached to it. Set the goal to be met around the time you expect to receive communication from the grad programs. Do your best to meet the goal. Once the goal is met you have something you will be proud of. Regardless of the institutions' decisions you will know that you can achieve what you set your mind to. So if you are denied (I pray you are not) you can look back and say, I was able to meet this goal I can meet another one.
