Just trying to survive with my sister

This is my first time doing something like this, and I really tried to avoid this (not knocking anybody else) but I need help. Recently, me and my sister‘s mom passed away from breast cancer. Our dad is not in the picture and Me and my sister are fairly young and I’m in between jobs right now because my car is jerking. And yesterday we walked 4 miles to spend our last for food. Today it’s raining and I’m scared we’re gonna get sick if anyone doesn’t mind helping us out so we can DoorDash something we’re not picky. It could be pizza or just anything I’m just really looking for help. Just anything would help honestly and thank you even if you just read it.
