so stressed out!!

So on Tuesday I go back to work after 9 months of being jobless. In December I had to quit my job because my daughter was diagnosed with cancer 😥 so me and my husband decided for me to stay home with her while she gets treatments, so far everything is going really well. I am just really stressed out on the fact that I am leaving my sick child at home, I know her father will take really good care of her no doubt in that, mayb the fact that I was so used to being at home with her kind of scares me that she will be sad or idk. But we are really short with money, bills aren't getting paid on time rent and car payments and killing us, we would be able to put some money aside for my daughters savings and now we don't even have 20 dollars to spend on ice cream when our daughter wants some. I don't know what to do I want to go back to work and help out with some bills but at the same time I want to be with my daughter and take care of her needs as well..
