I lost my dad yesterday

I lost my hunger, I want to sleep every single minute of the day, I can’t bring myself to go to school, I can’t help but randomly sob the times I am awake. I feel so lost. I don’t know how to pay a single bill, and now I have to take care of my mom and little sister. I just want to sleep forever. How do I deal with this? How do I do this without him. I’ve always envisioned my future with my family in mind, but now I can’t see any future. Can someone help me. I need help. I’m crying as I write this. Please help. Anyone.
