You know what? It's okay. We need to write about the things that are occupying our minds. I have also felt like I have flogged some topics but I needed to write about them...and still do.
I'm so sorry this has happened to your daughter but I am reading some positivity here too - she will find her way to what she really wants to do. And you need to give yourself a chance to have a decent break from all the worry.
Hugs to you, Susan.
