Congratulations, and you have my 100% support. You will need all of the things you mention, and two others -- good, consistent, non-judgemental support from another, hopefully knowledgeable, person; and good preparation.
Personally, I believe the sharing of the story is the only way things will change for the better for other survivors. If you look here you'll see some of the sharing I've done http://russwilson.coffeecup.com/my_story.html
It's only part of the story, and in part came about, not only after many years, but after the suicide of a friend, another survivor.
Around that time I came upon, through the internet, guidelines for how to share "lived experience" -- but I couldn't find it recently -- maybe lost in converting from one computer to another. Maybe Jane, or someone else, has some suggestions? Be prepared for the possibility that such sharing might re-open some old wounds.
All the best to you, always available via PM.
