Parents Whose children have been sexually abused Community Group
This group is for parents whose children have been sexually abused. We welcome both Mothers and Fathers. Here, we can offer support to one another. We can vent, cry and lift each other up. No condemning or criticizing allowed. We are here for support. We LOVE (((HUGS))) !
First things first, you need this resource: www.mosac.net. This is a very deep website that will help you to gain a better understanding of what this has already meant for your family, whether you knew it or not. Please know this: you did not fail your daughter; her piano teacher did. It's what manipulative opportunists do best.
Lots of therapists have experienced trauma. It's one of the reasons they are interested in the field. And lots of trauma survivors cannot remember why they are often anxious, sad, angry, etc. It's very perceptive of you to consider that your daughter may have worked through much of her trauma already -- perhaps she needed to do it in this order before she could risk allowing herself to remember.
Because this is actually new to your daughter as well as to you, you will probably all benefit from therapy (your daughter likely has her own therapist already, as required by the American Psychological Association, or by your own country's version of the same, if you're not in the States).
Your role in your daughter's recovery is, first of all, to ask her what she needs. Then, be a listener, and keep the discussion open. Beyond that, in my humble opinion, your focus should be on your own recovery, because you do not have the advantage of having spent years in a sort of a recovery-adjacent process, as your daughter has. I'm glad she's being kind, because it's what you deserve. Many survivors don't tell (even if they remember) in part because they don't want to cause their parents pain. But the pain is inevitable because we love our children. The old oxygen-masks-on-an-airplane analogy applies here: take care of yourself properly so that your daughter will see that you are a survivor, too.
