Bless you for considering taking care of your grandma. Not many people even consider it anymore. Especially when they are "sick" themselves.
I am the onl one in my family that has been the caretaker. I travelled 1200 miles to help my my mom take care of my dad. My sis and bro live there. Katrina had just hit my house, and I left my job, and hubby to take care of my daddy. I would do it again in a heartbeat!!! DH was SOOOO understanding!!!
Good luck. I hope all goes well, and just remember - PATIENCE!!!!
to you and yours!
