Just a question

With all of the abuse I suffered through, I have almost no memorie of my life as a child as well as an adult. My level of dissociation is profound . I am in therapy and have been able to connect to a super wonder and patient therapist who specializes in P.T.S.D. And dissociation ,and one of the things she does is called emdr? Which helps with flashbacks, teaches you how to deal with the memories that torture you all in a controlled place and I know I need to do this to get better,but I'm so scared to see anything else. I get that eventually I'll get more flashbacks and this method just helps to get things out in a controlled environment so I can deal with the memories properly. My flashbacks are consuming , and I need to stop running ,but as I said , I'm scared to death, so I was wondering if anyone has ever been through anything like this and if so, did it help? Also wondering if anyone has ever heard of guided imagery? Something else my thermistor has me doing which has helped!!!! I am sleeping all night for the first time ever!!! So I was just wondering if anyone ever heard of any of this? Thank you for listening, Sue
