Looking for somebody who has experience with RAD

My name is Patrick, I am 16 years old, and I grew up in foster care. My father was abusive toward my mother, my sister and I physically, emotionally, and sexually. Because of that, I was neglected physically and emotionally. Father was an alcoholic, and a drug addict, and my mother was busy protecting us, so she couldn't provide either. At the age of 6, I have myself, and 2 other mouths to feed, and I do that by robbing the local 711. At age 7, I went into foster care, and I was separated from my sister. My first foster family was just like my father, except I had food to eat. Barely. I stayed in that home until I was 11. At 13, I was adopted by 2 loving people who cared so much. But that failed, and I was unadopted this past October. Here's why. I couldn't love them. I didn't know how. I know there are parents on this site. How would u feel if ur kids didn't love u. If u have more than 1, I was their only, so imagine none of them loved u. What would u do? More often than not, I get the answer "I would still try." They did. For 2 years. I couldn't. I found out during that period that I had developed RAD. Google it, how it affects teens, and 90% of those symptoms are me. I came to this site looking for an expert that can help me, as I live in a group home, where there isn't a specific caregiver to treat it. I am fearful that I will suffer life long affects if I don't get it treated now. I have made friends, and even a gf on here, but I still would like some assistance. Anybody an expert??
