Has anyone been abused by adoptive parents?

I have and your not alone I have been emotionally mentally physically been abused by my adopted mother and sexually by my adopted father.I feel like I am alone because it happened as I got older by my adopted mom then at nineteen sexually.I now disowned my adopted mom years ago though.my adopted dad is deceased.I thought they suppose to love not hurt that's why I took it thought it was love and did not want to get them in trouble
