Yeah. That won't work. Welcome to Valheim and the Swamps. This is pretty much the hardest step for anyone who is not familiar with the game.

But let me tell you that once you got iron armor and the iron-banded shield, you can pretty much survive the rest of the current game, if you are very careful and are alway properly fed.

Good luck! You can make it. :)

Edit: Oh, and don't forget to upgrade your armor! Level three is recommended.
