Dear Amylynn,
My heart breaks for you and your father. There's not much else I can say here that anyone else has already said, but I will offer my hand in support.
Here is a website for an organization that helps with caregivers. My family and friends used it when I was sick. They found it very helpful and it helped to distribute the tasks that needed to be done so that all of the burden wasn't placed upon one person.
http://www.lotsahelpinghands.com/ They can also be found on Facebook.
They give lots of articles/advice about to caregivers in order to help them cope and to remember to take care of themselves during what is likely one of the most difficult times in your life.
I wish for you the strength to face each day and moments of comfort/peace when you can get them.
Take care,
Kerri
