Horrible staff and security...my child is in danger!

My daughter of only 12 yrs old is in the psychiatric ward. I as her mother believes that she is being victimized and being abused. I have to believe my daughter and she could be in danger so please listen to me. My daughter needs to get out this hospital. She cannot sleep during the night, everytime I see her she looks starved and always wants to come home. She has been put into isolation. Which was never mentioned to us in the first place,WHY? She was inappropriately touched by security. My daughter MUST come home please, can anyone at this hospital get back to me. I trusted them with my precious child. She is not a substance user, she is not a problem child. She has been through a lot. She comes from a decent home. We love her immensley. Help please!!!!!!!
