I am trying to write my story (on the computer) to help with trauma, but it is very complex and traumatic and I am struggling to write, I get to a dead end where depression or traumatic memories stop me from writing, and guilt, because the people who have hurt me told me it was my fault and tried to make my trauma and pain out to be insanity (and failed).

Has anyone got any advice as to how to cope with writing.
I am sure that it will help me to write it and what I have written so far has helped me.
