Hospice care will help both him and you. You need some rest to be there for him. Hospice staff knows how to make things more comfortable for him.
There is also Palliative care. Please, you cannot continue to do all this on your own.

I pray that God pours His healing grace down upon your husband. Father God I lift up this wonderful wife, who loves her husband to you. Please give her the strength and discernment to make the best choice for her husband and herself. Father, I thank you for healing grace and the love You have for this family. It is in the mighty Name of Jesus I pray. Amen
