Your biggest problem is food.

By that time you should, at a minimum have carrot soup and boar jerky to go with your cooked dear (if you have a lot of blueberries make Deer Stew instead of just cooked Deer Meat). Boar jerky is made from boar meat plus honey in a cauldron. You get honey from beehivees you make after getting queen bees from wild nests in buildings in Meadows. Carrot seeds are found ion Black Forest, you'll need a cultivator to grow them and it'll take a couple game weeks to build up enough seeds so you have a reliablely sized crop of carrots every 4 days.

Your second biggest problem is you are using the wrong shield (except in special cases). You should be using a level 3 bronze buckler and learn to parry (practice on boars and necks in Meadows, and grays in Black Forest). On successful parry, it blocks more damage, uses less stamina, and has a decent chance of staggering the enemy compared to the bone shield.

Your third problem is your bronze armor is only level 2, it should be 3 by that point.

Hope that helps, good luck!
