Frazzled...contemplating home/hospice care

I am just completely fried from working in a Skilled Nursing Facility that has nearly sucked the life out of me....I did home health as a CNA for years, but have been hesitant about Home Health as an LVN. I think my biggest concern is worrying that there won't be enough work, (at least 32 hours a week) I don't want to work for numerous agencies, I'd like to work with just one, possibly 2. I know some agencies offer benefits, but how can they do this if the hours are not quaranteed? Any thoughts or help is appreciated....
