We discuss similar things in my therapy. For me, it's not to cry about it or get mad about it. I have trouble remembering a lot of detail from my childhood. My therapist has said that it doesn't matter if I can't remember what happened, that it's obvious that my emotional needs weren't fully met as a child because of my reactions in therapy and how I feel. I find him telling me things like this useful because it helps explain why I am like I am.
