Writer's Block

A few days ago someone left the link to call for submissions to a book for breast cancer survivors in the comments on a post. Because they didn't say anything else, I'm going to interpret that as their suggestion that I write something to submit. You can read what the criteria are here, but basically they're looking for stories about experiences with breast cancer. It should be positive and uplifting or encouraging. Given that most of what I do here is whine, are there any topics I've already talked about that you think I should explore further for something like this? If you found yourself in a similar situation, what would it help you to hear? Any favorite posts I should share with the world? Let me hear what you think in the comments!
