Maybe because you are a smart lady, and active in your healing process?

I don't know in what fashion you learn, nor how you generally get things done... that would help me help you. But I will try...
what about going through a book about abuse and checking off those things that are similar to your experience?
can you use/write down one word for each part of the trauma? Anything at all will help you... year, month, date, day/night, place/location, colors you recall (clothes, room, etc)
maybe just write one thing down first, and put it aside?. Later, write one other thing and put it down?
if you can't write it, can you tape record a list of info - speak it?
if you can't write or speak it, have you tried doing a collage? (cut pictures from magazines depicting parts of the trauma, paste them onto paper)
if you are artsy... use chalk or oil crayons, you don't have to write words, let each color or pattern represent a different part of the experience (such as the red dark/pressured straight lines are your anger about it, blue circles are your breath)
Maybe nothing here will work just like I posted, but you can think of something that will suit you in a like manner?

Be gentle with yourself.
Maybe speak to yourself before falling asleep, and ask that you have a non-bad dream about it? (will help you release it...and then write about the dream elements)
Would you like something like a 20 questions drawn up for you to give short replies, would that help? I'm sure others here could help with that. Sigh, I hope you are able to do this... it is tough...but it gets a bit easier after this...
