The State doesn't get it! Help!

I am the foster-adoptive mother of an 8-year-old daughter who came to her father and I when she was 9 months old. She is severely RAD, but short of violence. She is destructive to material posessions but NOT to people (and not to animals! after years of intense coaching!). Due to her severe behaviors and my own health concerns I made the unbareably horrific decision to put her in theraputic foster care. This was only after spending dozens and dozens (if not hundreds) of hours researching options. Thankfully, we have been extraordinarily blessed to have found a theraputic foster home placement for her that is healthy for her, close to me and had a basic understanding of RAD before receiving her. Due to massive budget cuts to the Department of Social and Health Services (DSHS) in the State of Washington, the case worker and her supervisors are unwilling (or unable) to even consider granting me a guardianship or long-term foster care placement -- keeping my daughter in her current placement for the forseeable future, while allowing me to still visit her regularly and be "mom." They have filed a petition to terminate my parental rights. My soon-to-be-ex-husband and daughters' foster-adoptive father has repeatedly made clear his desire to relinquish his parental rights. I have no intention of doing so and will fight it until my dying day! I love my daughter (and ONLY child, adoptive or otherwise) as much as any mother can. Tragically, due to her RAD, ADHD, Generalized Anxiety Disorder and Bi-Polar Disorder and my own health concerns we cannot live together full-time. I have never neglected or abused this child (or any other child for that matter) yet I constantly have to defend myself to the social worker. In an effort to create a paper-trail pointing to termination the State has now reduced my visits to 6 hours a week. Prior to the reduction I saw her anywhere between 8 hours and 54 hours a week. Their argument for doing so is that they're experimenting with making the visits exactly the same time every week to see if it has an impact on her behavior. I would LOVE to find an expert, and/or a quote in a book by an expert that would squash their premise. In my opionion, and based on what I've learned about RAD, controlling her behaviors is best done by theraputic attachment parenting techniques--NOT through limiting the amount of time the child has with the person she's most attached to in the world. Any assistance in this area would be GREATLY appreciated! Thank you! And good luck to all of you other parents of RAD kids! ~ ShelleyC123
