Winnie,
I'm sorry I didn't see this last night to give you some encouragement. You have been through it all and this is just the last ounce before your son is off. I will be thinking of you today and I hope when he is in the rehab you have a chance to take some time for yourself............you so deserve it.
If it is not to late please tell your son we wish him well and we are looking forward to his recovery.
