Don't feel bad, this game is by far the hardest in the series, and nothing like the rest of them. I've been playing Zelda all of my life, and I died 40 times in this game. I have never died that many times in a Zelda game, I think the worst was 30 in LoZ. Like Michael said, just stick with it and you'll get better at it. I advise grinding a lot and mastering swordplay, which means learning when to crouch and slash/block, and when to stand. Also, learning jump height and timing with the sword while in the air is very helpful. The best thing for you is to fight regular enemies over and over though, because it makes you stronger and gives you practice.
