exhausted from trying-considering crying uncle

I know I'm a bit late to this thread - I've been off the boards for a little bit. I had a 3 year old who came to me as a concurrent placement this spring. It became apparent within a few weeks that behaviors were far more severe than had been expected (or at least than I had been told). I gave notice just over a month in that the child would need to be moved. I only parented a child with RAD (who I had been assured wasn't) for 6 weeks, and I thought I was losing my mind. My son was starting to act out at school from the stress, I was physically sick from it, and one of my friendships was destroyed. All in 6 weeks. I have a friend who adopted a child with RAD, and I see what she is going through and the toll it is taking on her family. There is nothing wrong with saying you can't meet a child's needs. It is so much better than saying you can and not being able to.
