Zombie apocalypse. (Survival)

You are at home, preparing lunch as usual, you live alone. When you finally sit down to eat, the sound of an explosion echoes through the street, you quickly get up and go to the window on the second floor of the house so you can look over the walls. On the street, several people are running and screaming, some are even eating each other!
Two weeks have passed since the start of the outbreak, you've been locked in the house all this time... but food is already running out...
