I am in a very similar situation. I applied to a Masters program in Biology in April which had a June 1st deadline. I had not heard anything since mid May, so mid June I started callng the admissions office. The comittee told me that decisions were being made and all of the letter were being sent out and I should know by the end of the week. It is now a month later and still have no decision. I have left messages and no one has called me back. I check the mail, email, and answering machine everyday and no answer yet! You are not alone don't worry!
