inability to recall personal information

What could that mean exactly or what does it feel like to those that experience that? For me it's like the information is there somewhere but I can't grasp it in the front of my brain if that makes any sense so I just say I don't know because it feels like I really don't know anything about my childhood or my life. I do know my social security number, my birthday, which bank I use so my question is, is that important personal information? I need a little clarification. My new T wants to start reviewing my history including my childhood and I have some anxiety about it because I'm so all over the place with my information and nothing is in sequence at all but she's says I'm doing really good explaining things but I don't think I am. As I was leaving last session I told her I would try my best to tell her about my childhood and she made kind of a confused, weird face so I don't know what that was about.

Yes that is all good and much needed information to have. I know what it feels like to not remember things of your childhood, like i'm sure we all do. For example sometimes i can pictue a house i lived in and some of the rooms. But for the life of me i can't see or get into my bedroom. Or maybe in other houses it might be other rooms, the basement for example. And i totally have black out, in regards to my younger brother, 5 years younger than me.
I think in regards to how your T looked at you, the best thing to do would be to talk to her about it, if you feel so moved. Also what has been helpful for me is to sometimes work on things by doing a timeline. It might be helpful to look at your childhood like that and then share with your T. I have started from the beginning, or we moved around alot, so i would try to think about what was going on in regards to different schools i went to, and relationships i had then. Also paying attention to notice ing where are my biggest blocks of time? It has been helpful to me to look at my childhood from different points of view, and also just openly talking outloud to my system, or individually to encourage safety for the ones inside that do hold those memories to please share with me. And if they don't feel free to share with me to discover and work through all the reasons why they don't. Blessings
