To be really honest, I think you emphasized wrongly here and should have emphasized 'she', instead. Now it totally reads awkward and the whole message is undone by the confusion it causes. One could debate that the 2nd comma is overdue as well, but lets not nitpick now.
Anyway, I think you're having a hard time trying to prove your worth. If you have to try hard proving your worth then.. well, we can all make our own conclusions.
Why so tense?
