Hmm.. I'm not sure if it's the same. But my brother has something similar? Anyways we have been in fostercare for about 1,5 years now. Whenever we were split up he wouldn't talk at all. Only to me when I visited him or talked to him on the phone but even then not a lot. Also he has leukemia and when he's in the hospital, same thing.
Do you have anything that helps you deal with this?
Take care,
