I already have gone through the question of whether abuse took place in your childhood or not. I understand that you don't have evidence and the only indications of possible (and IMO very probable) abuse are some memories you've recalled recently. All I can say to you is that I believe that you were abused in childhood based on what you have reported so far and based on my professional and personal experience with this issue. I can't say that I know what happened in your childhood. Do you understand the difference between "I believe" and "I know"? So, I do believe that you were abused, but I don't know that.

Since you don't have evidence of childhood abuse, this is exactly what makes your situation complicated and difficult for your therapist to work with.

That being said, it is not her job to become an investigator and to collect information from outside sources like your family. You are an adult and you are the client. She is supposed to be working with you only and to deal with the information you give her the best she can.
