All I know to do is to be there whenever he needs me, tolerate some of his defiance but know when to put a kabash on ill behavior when appropriate but most of all put all my worries into god's hands and let it go.
I know that god is a fair and just god. He does not lay more on your shoulders than one can handle. He hears my prayers and acts in kind to what is his divine will. Still I just don't see why my son is the one to bear such a burden? There has to be an answer somewhere but I haven't come across it yet.
Pray, pray, pray for Jacob and ask for strength to help him through all of this. Pray that I have the wisdom and strength to carry on and meet my responsibilties to Jacob and all other things in my life. Please guide us to theother side of this nightmare and bring peace to my son most of all. Amen
