Chin up buckeroo.
I spent all the end of October and all of November waiting on my first acceptance letter. I had interviewed at five schools, and none of them said anything at all for 9 weeks.
Typical PMS. Walking excitedly to the mailbox only to find that the big envelope that you suspected could be an acceptance letter was just a letter from Ed McMahon telling me I may have won 10 million dollars.
Then on Decmeber 7 I got a letter from one of my top three choice schools. Relief set in, but I still wanted to know where I stood with the other schools.
Nervous calls to the FAO of each school yielded nothing more than the same information I already knew.
Then it happened. Yesterday I got a big letter from my state school. The school that is a rocks throw from my home. The school that I thought of when I pictured myself practicing medicine. My top choice came through. Not only did they come through, they did so in very short order.
The letter was dated just three weeks after the day I interviewed. In spite of being the last school to interview me (five weeks after everyone else), they were the second to accept me.
The moral of this story is that if you are interviewing as frequently as you said you are, and as early as you did you are a very good candidate. Be patient and stay strong.
Remember, there are many people out there waiting for interview invitations the way you are waiting on acceptance letters. You can help eliminate this anxiety in others by releasing the hold on those multiple acceptances as early as possible. Then some other person whose first choice is the school that you are accepted to can get "the big letter" sooner.
