I'm guessing you may still be down in FL since I'm not hearing much from you. Caring for aging parents...as we ourselves start to slow down, can keep us busy.
May the Lord bless your mom and her doctors and bless you and keep you in Peace and Strength as you continue your vigil...and may he guide you to care for your own health needs and not become lax that you lose your strength.
Keep the Son in your eyes, bro.
