Are there services that can help me in keeping my house and affording it, because without my husband's income I can't afford it?

I am having a very hard time deciding how to move forward with this process. It scares me because financially I can't do it without assistance. I know I would get child support but that still won't be enough. The decision to get divorced is one that has not come to me very easily but is necessary for my children's sake and for mine.
