@jesclarke07,
I guess she'd be 17 now and I hope she's doing well.
She's been in care outside her bio family since she was 3.
I'd imagine she has the resources to find you and her other family should she ever want to. From what I understand it usually isn't until they start considering starting a family of their own that women who have been adopted start trying to find members of their biological family.
I understand your concern but I think you should wait to hear from her instead of trying to find her.
