In my opinion, Pete Walker book, Complex PTSD: From surviving to thriving, is an absolute read/apply if you have a complex trauma. Complex PTSD have a range of symptoms as you gonna see in the book. what I suggest doing is pin pointing the most persistent issues, such as Perfectionistic thinking, abandonment mélange feelings, toxic shame, etc, and try to work individually on these issues. Pete Walker book is the roadmap to start with, but in my opinion it takes more than that toward recovery. Toxic shame for example, and after psycho educating yourself, you will relate to it a lot and you need higher level work such as Gershen Kaufman books and John Bradshaw books too to work on it. I mentioned toxic shame in particular because, and Pete Walker agrees, no CBT or psychotherapy will advance the recovery unless you address this problem. A lot of patients don't get that much from therapy because the therapist don't try to heal the Toxic shame first.

Cognitive self help books don't work alone, emotional healing, esp grieving work is also a must according to Pete Walker, and I agree with him, since I tried to advance my recovery with a lot of CBT bull **** without any avail.

My best wishes
