"Yesterday was Thursday. Today it is Friday." No, we're not trying to give you a lesson on the days of the week. Those are the lyrics to teen singer Rebecca Black's song, 'Friday,' which has the Internet buzzing about whether or not it is "The Worst Song Ever."

After earning more than 16 million YouTube views, becoming a top Twitter Trending Topic and landing at No. 31 on the iTunes Top 100, Black should be celebrating. Instead, she claims she's found herself as the target of hurtful online bullying -- something she's trying not to let bother her.

Black was interviewed on 'Good Morning America' and spoke out on her fast rise to fame and the hurtful comments she's received.

When asked if the past week or so has seemed like a dream, Black replied, "I really do. I can't tell whether I'm awake or not."
