It is normal to be killed like a hundred times at the beginning of this game, especially if you have never played a Souls game. Don't worry about that.
You're a hunter, you're supposed to be able to deal with the dangers arround this place. Other people only can lock themselves into their houses and hope for the hunters to stop this never ending nightmare.
Never fight more than two enemies at once. Explore every square, every area, every alley in the game. You'll find shortcuts that will help you to not being repeting the same long path over and over again. When you open a shortcut, it will keep open even if you die. Don't be afraid of using vials, you'll find more. Dodge. Use your gun when a strong enemy is about to land a blow on you. If you do it at the right time, he will fall down its knees and by pressing a button you'll perform a visceral attack that does TONS of damage.
