One thing I am looking into is the book "Running on Empty." It's new and is written for people whose traumatic experiences in childhood were due to invalidation, neglect, and emotional abuse (in other words, the problems was caused mainly by what you didn't get in childhood from your parents that you needed, rather than the bad things that did happen to you.)

Internal Family systems (IFS) work with a t can be very helpful for working with the inner child too.
