Child welfare and foster parents are submitting dishonest updates to the judge- how to revok them, Clark county Washington

My son was removed out of my care last February under false allegations. Allegations of medical neglect which is far from the person I am I would never do that to my child. In fact I advocated for him until a doctor finally gave me answers I was sent away by many clinics and emergency rooms told nothing told they couldn't deal with anything to help him. So when I finally was able to have some answers DHS ended up getting involved saying that I was medically neglecting his needs which is absolutely absurd I decided that even though he's out of my care for the wrong reasons that I was just for even get this case over with and getting back cuz I'm scared to file anything b******* I need to file something they are getting worse and worse now they're allowing the caseworkers or caregivers I'm sorry to submit false updates false update saying that the father and I returned him filthy he's lethargic and he's just a bunch of crap that's not true what can I do my court appointed attorney said that I cannot file anything to rebuttal the false allegations the false reports and updates that's not true I just know it's not true what can I do
