I don't think that everyone experiences trauma and I think that CSA is a very particular kind of wound which affects us in a uniquely deep and painful way which others cannot understand. Having said that, a diagnosis of CPTSD does not tell people that you have experienced CSA. I think when our boundaries are violated in such a despicable way at a young age, it is really hard to understand that our being exists beyond the abuse. We are not the abuse, we are not disgusting like the abuser, these acts were done to us but we are not described by them. The shame belongs to your abuser. CSA is not written on us. CSA is a specific trauma, but a trauma diagnosis does not tell anyone the details of your past. It is entirely possible to heal without a diagnosis or whilst ignoring your diagnosis, indeed there are whole mental health movements which believe that diagnoses are unnecessary and regressive.
