I can understand what you are feeling. When I get very distressed I can feel and appear very childlike... I have talked w/my T about the many different ways and ages I present...It can be confusing as many of us who are Dxd w/ DID or any other DD usually carry more than on dx.. my T and I have spent some time trying to separate and identify this tangled ball of Dx yarn .. So in my case, If I am somewhat aware of this kind of state but may or may not depending on trigger/situation....we have attributed this to PTSD. If I present childlike in full amnesiac state (completely unaware)... Considered a DID part...unless the child identifies as legal identity and is "stuck" in a past timeline...then PTSD "flashback". In some ways I always feel childlike. The teen stuff...I have been told happens, but never to my awareness. Though, I have been informed of a few teenaged "alters" (I dislike that terminology...I prefer to use "parts")..these parts have nothing to do with my known time line or life..completely autonomous...therefore DID...w/ 1exception...I am unaware of this part when it presents, but have found notes left by her, which hand writing and time line match some of HS notes that I have kept.. but are not notes that I remember writing and do not match my teen age hand writing.. This is where it gets confusing to me at least.. I am also dxd w/ BPD. BPD does not present until teen/20's... I have a part that I have over my life been both aware and unaware of at different points in time. She has been identified as 1of 3known parts that have existed since memory serves(I am another one of these 3)... Her primary function was "protector"... but, she has also been identified as my BPD counterpart as well...being that I am unable of sexual intimacy and extremely uncomfortable with even familar/friendly physical contact..some of which I have been able to desensitize towards and am now OK with very close trusted ppl hugs and occasional kiss on cheek or forehead...but no more than that...so, once puberty hit my protector part took on role of sexual part as well..tho apparently there are other later presenting parts that are also capable of sexual acts as well, but when eventually mid 20's was dxd as BPD, she has "owned" the sexual, implusive, flighty, extroverted, angry etc..behaviors. .which are,associated w/ BPD. Some I have bits and pieces of memories of some not at all.. I display the dependent depressed, attached behaviours on the other side if the BPD coin...so this on teen PTSD "flashback" part identifies and presents as a younger version of her... IDK if that makes any sense?? I still struggle with a lot of this. I intellectually understand in theory...but still it makes my head spin.
