Is it rude?

Okay, so I e-mailed a lady from OSU about talking to her about pharmacy school two weeks ago. I haven't heard anything back. Would it be terribly rude to call her? Should I be discouraged? I'm trying not to let it get me down, but I can't help it. I had such high hopes and now I feel like her silence is telling me that I'm not going to be good enough for pharmacy school. But that's just silly talk. Right?
