Welcome to Soulsborne. You are going to hate this, but if you stick to it, you are going to love it
. Whole game is like this (except bosses and special enemies like hunters).
Respawning enemies help you to "git gud" and also help to lvl up. Repeated encounters help you to learn their moveset.
Save points (lamps) are scarce but there are a lot of shortcuts you can open, which always lead to former lamps. So advance really carefully. If enemies are to tough, avoid them / run past them (two big wolfes) or cheese them or divide them when in groups and 1on1 them. Have fun.
Good tip is: dodge forward/left or forward/right into an attack. You have a small window of invincibility. In the beginning you instinctly dodge back or sideways but forward brings you right besides/behind enemies/bosses for good damage.
One of the two first bosses (graveyard) will be really tough as beginner
but after it, it gets better.
