Oh, Carolyn

You are bearing an impossible load. I wish we could come alongside you and take some of the burden.
My DH has had a similar(though not the same) experience with his illness. He has stage 4 lung disease. His health is very fragile, and eventually this disease will kill him. DH never smoked in his life, always execised & ate right. Our lives have been up-ended by this illness. Sometimes I just want to scream "THIS IS NOT FAIR!!"
I don't know if you have started the application for SSDI but if not, now is the time. I'm very sure your DH would be awarded SSDI due to the severity of his illness. SSDI won't replace his whole income,but it will relieve some of your load. I would also talk with the hospital social worker or your local health department about applying for whatever catastrophic coverage your state has. Once your DH is approved for SSDI, they will probably put him on Medicare pretty quickly due to his condition.
As for your poor little girl--

I know this is so hard for you and for her. She may not understand what's going on *and really, do any of you?* but she is absorbing all the worry and fear in the household. My DD was about 10 when DH nearly died from septic shock. He was very ill for a long time and our who household was turned upside down. Fortunately, her school guidance counselor was able to help us. She got DD hooked up with the "Friendship Club", a group for girls who were experiencing grief or serious turmoil in their families. Once a week, the GC took DD out of class to join her with the other 5-6 girls for their 30-min "club." Sometimes they made collages or necklaces. They made crafts and told stories about their families. DD went to the Friendship Club for 6 months and never knew it was a therapeutic group therapy. But it really helped her get re-grounded.

I know this is a terrible time for you. As the caregiver, you have to keep all the balls up in the air and it's not what you signed on for. It's okay to be angry, sad, irrational, and weepy. You don't have to have a specific reason. If you find that it's getting to be too much for you, consider seeing a therapist yourself who can help you through this awful thing.
