My heart goes out to you Roger, sorry about this happening to you, like the other mentioned, it's good to get things off your chest.
I commend you on being a foster parent....I know full well what that's about, and I know how easy it is to get attached to children, they are like your own after they've been in your home. I think it's great she called you, and called you Dad....that should make you feel pretty darn proud of yourself, you did a wonderful job. I know you're in pain, I hope you find some peace in this.
Take care of yourself.
Hugs.....Denise ( I cried for you)
