hi lily, yes, definitely share that with her. i'm sure she'd be willing to watch it as it might help you a great deal. i don't think it's that different than listening to you tell her about an abusive event from your past, it's just a different form of communication. either way, i think therapist are trained to handle all this kind of stuff. but i think i'd ask first, just out of respect. it might be something that you both have to "prepare" for.
