Jays Mom,
Welcome to NeuroTalk. Sorry to hear about your son. I know many here in Idaho with similar situations. We meet at a Brain Injury Support Group. It has a caregivers group that helps caregivers connect with others for help and shared resources. Many had to relearn it all.
I suggest you check the Brain Injury Alliance of Washington .

They can help you with resources.
Feel free to start a thread in the main area if you have questions.
My best to you.
