Perhaps you need a break from this site? Stop talking about it at least for a while? The mind chatter about the Borg fades, really it does. I understand that in some ways we cannot get to the end of the traumatic experience because our relatives and friends won't listen and the cult still exists.
I just worked on not being angry, getting qualifications and getting a job, a house and a life. There isn't any closure, I understand. Just work on making it fade and being busy enjoying your life.
