Snow,
This is a most interesting post to me. A few years ago my youngest son had brain surgery and I was falling apart surrounding the experience. Coincidentally at the time I was taking a writing course. I decided to write about the experience in a fictionalized context. Believe me, it was thinly veiled. I gave myself a new name and wrote about it in third person. It was a very healing experience.
I hope you can do this for yourself. Just pretend it's someone else and you might have success. Of course, with my habit of harboring unintegrated parts I may be a bit more experienced, but give it a whirl, you may find it helpful and fun.
Peace
