How am I supposed to finish the game without healing?

For context: I never actually got the platinum for any game, so I decided to try with RE3 remake, since it is the shortest RE game, it has been going smoothly so far, I got rank S on standard and I was going to try hardcore, until I saw the achievement in the picture . Dude, I already suck at RE games, and now I have to master the parry mechanics? Are there any parts in the game where your health heals automatically, without you having to use herbs, and do you guys have any tips for getting better at the dodge's and parry's with Carlos?
