IMHO it is easier for you to address CSA if you focus on the part about your brother and needing to protect him...What about what sweepy needed???? That is the part that T & sweepy need to work on and you are going into untraveled areas of what happened to you not your brother. You are going to have time between sessions where you will "process" what you and T talk about...I promise it does get easier and feel that new T is a safe person to help you. Hang in there!
