Help me fight for the rights of children who dhs took and won't give back

My name is Kadijah McKee. I am 21 years old. My son is two years old and my daughter is one years old. Department of human services took my son from the hospital and said I was homeless and tried to say I had a drug problem. They gave me three randoms drug tests and I passed all three.T hey came out to my house and I passed my home expection. Then they tried to say that i am unable to care for my son because of my sexuality. Approximately a year later I had my daughter the took her from the hospital also I had stable housing and had everything I need to care for my children. They told the hospital that I wasn't able to go see my daughter and she was in the ICU nursery due to weight. When I ask why was my daughter in care they could not tell me. So I went to court and I completed everything on my court order and I still yet to get my kids back and now they tell me because of my sexuallity I am not able to take care of my children and I don't think that is fair. I would like for everyone help so that me and other parents like me can get the Justice we deserve.
