I think it's because Rainbow gave her confidence during Hurricane Fluttershy and she was able to face her inner demons during said episode and overcome them for Rainbow Dash's sake. She was overcoming her fears for her best friend.

In this case, she doesn't think she has Rainbow's moral support anymore. Though Rainbow will probably set her straight and tell her she's a great singer.
