Ah, I am sure thats because she is busy. She has been very busy lately. I don't know what you said, but she's pretty tough, I don't think she would have taken it to heart.
You should apologise to her directly though, not through other people.
This is why sending people hate mail is a bad thing though. You don't know what people are dealing with in their life away from the internet and it could be the last straw in a very very stressful life, so you need to be careful! If you have nothing nice to say, don't say it at all, or at least not directly to them. Even though the internet makes you anonymous, your conscious knows.

But we all make mistakes, then we learn from them :) *pat pat*
