My advice would be to start reading and you’ll soon know how you feel about the writing project. Whatever you decide, consider keeping some of the meaningful (positive) messages – they might be nice to return to.

Dear Anne, I can relate to so much of your story, as I have similar boxes. Once in a while, I read a bit. It does stir up memories. Some are painful and some are quite pleasant. The bad memories are less painful now, though.
You are such a good writer and communicator, so I think you can tell your story in a way that would help yourself and others. With warmest regards, Bea
