I've been working on my personal statement and a doctor I met before offered to read it over for me. I sent him my essay via e-mail on Tuesday this week but he hasn't reply yet. I just found out from a friend that she hasn't receive my attachment e-mail either. I am worried that the doctor did not get my e-mail as well but I'm afraid that if I sent him again, he might think that I am rushing him. I don't want to be rude but I want to make sure that he got it. Any suggestions on what I should do?
