Kite Runner chapters 23-24

I really thought things were getting better in the last couple chapters. I really hope that Amir is able to adopt Sohrab but I don't think Amir should be promising him anything if he is not sure he can keep them. Did Sohrab really try to commit suicide in the bathroom? What is going through his head? I wonder what is going to happen in the last chapter with everything that is going on.
