Lori,
I can't imagine dealing with all the issues that you have on your plate. From your previous posts, you are doing a fantastic job making the most of the options that your have! Your son sounds like a wonderfully empathetic, caring and intelligent child. You are an involved active mother in providing him with all the options that you can.
Caring for a family member that needs special care, while an act of love, is exhausting and draining. The situation with you mother saddens me greatly while at the same time reminds me to treaure the time I have with my parents!
