Haha, I felt very similar. I remember after I had my interview for nursing school, they told me that the letter would come in three weeks. I felt like that was a precise number, so I was expecting them to hold true to their word. Three weeks came and went. Every day while I was in school my mom would bug the mailman and ask, "Are you sure that's all the mail you got?" Four weeks came and went. Somewhere in week five I got my acceptance letter. I was so nervous to open it, so I did it very slowly. Eventually I saw "congratulations" and I ripped that enveloped open to shreds. I did a dance and cried in my room.
And then I, too, became anxious because I realized I had to get a ton of stuff done. I got accepted at the end of April and had to have all my immunizations, physical, background check, dentist appointment, and CPR done by June. I must of had like 20 papers to mail. I checked that I had all of them at least 15 times neurotically the day before I mailed them. Then I checked then again and again and again.
Phew... okay, but then I wondered when the orientation information and class information would come. I was worried about that as well. The acceptance letter told me I would receive an e-mail sometime during summer, which sounded very ambiguous. I finally received the e-mail, was able to register for classes, and found out that my orientation is on August 13. I feel like a huge weight has been lifted off my shoulder.
Don't forget to breathe, you will find out soon enough. If I was able to get all those things in on time, so can you. Good luck! :)
