If it was me in this situation, I’d make a travois and pack it up with whatever food and tools I could use in a long journey, using logs to keep myself warm on the way.
If you can, follow a road until you find a town - if you’re deep in the wilderness then pick a direction and keep at it.
However if you’re completely avoiding civilization, then I suggest finding a swamp. They’re a bit dangerous, but you could find a huge amount of supplies, namely salt, plant fiber and starch/flour if you can process the cattails.
Using logs and other materials you could eventually make a bow to hunt game and craft warm clothing, have ways to preserve food and even build a small log house and fireplace. From then on you’re good to go
I forgot to mention that if you’re lucky you can find a helicopter crash site (indicated by a massive metal wreckage) you can salvage this metal and can make a plethora of items from it, not to mention if you’re lucky you can find some military grade gear.
