There is something a little exploitative about what she's doing here. Some parading of her talents and emotions and opinions and anger with a long resume of her credentials affixed (Go here, for example)-- a public display of things most of us would want to keep private.
But I suspect she has some ambivalence about what she should do and how she should feel and a lot of things are going through her mind now. She felt like this at the time and couldn't resist writing about it and sending it in to be published. How she'll feel about it tomorrow or the next day, I couldn't say.
