Your source of food and drink will be rabbit farm and goat farm and fish, *to build the fences u MIGHT use dead fir logs laying on the ground in the forest. And also u will build some random shelter for them during rain.

From the rabbit farm u will get meat organs and the fat around the organs and blood, 1 grown 4 weeks old rabbit has around 250ml of blood.

Goat farm will give you especially Milk and more fat because of the milk and additional bonus medium sized animal meat , (u can have as many goats as u want OR 2 female goats and 2 male goats and their 2 babies will be for bonus meat, organs, blood fat etc) Also milk will be stable because goats produce milk for 10months.

You will also fish from the river/lake for easy fresh food, u can use fishing rod, or make/buy a small basket, drop some raw meat in the basket, submerge it in the river and trap the fishes inside it

Your drink source will be raw milk and blood and the lake/river water, Medium sized river is important because it guarantees you that it wont dry out and it gives you and ur animals source of drink.

Since you will eat and drink uncooked u wont need any electricity or ovens. You also wont have running water so u will shower in the lake or river.

Some concerns might be the lake or river freezing up but i doubt that this would such a big problem because u can break the ice or make small holes in the ice to fish, but even if the lake or river would freeze up completely you still have 2 more sources of food, You can also then collect rain water to drink instead of drinking river/lake water

The biggest concern MIGHT be the winter but when you eat raw meat and raw fat u get very resistant and tolerate well cold weather and u also will be in ur cabin. You dont need to worry about your animals in winter also because rabbits and goats tolerate winter/ cold weather very well

You can also gather food from the massive forests around you, like dead animals, maybe frogs, squirels, birds to naturally spend time. You also can create weopans

IN the worst case when u loose your animals u might just hunt in the forest
The possibility of breaking your arm/leg is also worth mentioning

These wooden cabins are cheap

Here is the medium sized river
