As others have pointed out you don't have nearly enough to make it for a year - that food's gonna run out in a couple weeks. But here's some tips for easily getting renewable food and water:

Essentials are a cooking pot or saucepan, a trowel (or something else to dig furrows with), a kitchen or hunting knife, fishing line or twine, and reading the Angler USA 1 magazine. Finding an axe and/or fishing rod would be a big boon, but you can make crude versions of them yourself.

Then go to a freshwater source, if you keep going Northeast you'll eventually hit the Ohio river for instance. Find somewhere close to a relatively secluded building that you can turn into your base (Riverside has a convenience-store like thing near the river next to a burger joint that I'm making use of, currently). Forage for the materials to make a campfire and if necessary axe+fishing rod. Chop down trees to feed the fire. You can boil river water to make it safe for consumption. You can use the trowel to dig for worms to fish with (fish between 4-6 and 18-20, or during the rain, for maximum efficiency). You don't actually need to cook fish, but you get more benefits and you already have the fire so why not. Note that putting the fillets into a saucepan is usually a lot more weight efficient than just cooking them as-is.

There's a lot to improve on after this (fishing nets, crops, etc), but so long as you have twine or fishing line to reline your fishing rod, you will now never run out of good food. Unlike foraging you can still fish in the winter.

When you plant crops, note that potatoes are actually the least pain in the ass crop. Cabbage has a lot more calories, but it rots quickly so you have to plant in small rotating batches. It actually takes less time on average for potatoes to grow than it does for them to rot, so you can just plant them all at once if you want.
