Struggling Financially

Lately I feel like a failed parent. My husband works well over 60 hours a week so I stay at home with our kids. We can't really afford daycare even if I were to go to work. We used to be so financially set but then we let family members stay with us for a few months and now everything has gone downhill. I'm just wondering if anyone else has been there and how they stayed positive through their hardships. I can't even afford our bills let alone Christmas gifts for our kids this year 😭
