Don't really understand what sort of assistance you're asking for:
- information about how trauma affects neuropsychological / social cognitive processes -- the formal stuff -- van der Kolk's book "The Body Keeps the Score" is great for this
- resources for doing this healing
- personal stories
There're heaps of resources -- many available on the internet -- for this topic -- attaching one I just downloaded that came with an automatic alert I set up in Google
Of course, if it's the last, it's the hardest to do, sometimes, yet often what appeals most to the buying public for your book
