How would you survive the apocalypse, what do you need to survive for a year?

I was wondering, if the apocalypse strikes tomorrow, the economy collapses, how would you survive? What would you need? I want everything to already be in the house, what do you need to survive for a year or longer? Not just survival, but also if the collapse happens overnight and tomorrow everything is unavailable. Like water, food, everything. Like the whole economy is collapsed, what do you need to survive? I don't pity people who say "it'll never happen." I'm prepared for it because it's my decision, not yours, but also the economy is already collapsing, and they want to make the currency useless. I want to make sure I'm prepared and everyone knows how to survive. I'm already making more than enough money, it's not expensive if you know how to survive. I already have water, I have already bottled the water, more than 1000 liters already, I know how to purify water if I want to use it from the tap. This is one of the most basic needs, but most people forget it. You can survive for a week without food but not water. You can't pity people who buy gallons of water and hoard it. It's your decision, I'm not forcing you to buy anything, but if the economy collapses, you'll be the one who will be searching for water, and you'll be begging. Like they say, always be prepared. Like the old saying, "A pity is knowing them than it is unknown to them." I think people forget it. You should buy the things you need the most, stock up on everything you need, because even water is expensive these days. You'll be the one who will be searching for water pitying yourself. Like I said, always be prepared, because the economy will collapse. You can't trust it, you need to save up and be prepared.
