What should I do?

I know this is the kind of question you probably get all the time, but I really don’t know what to do.I've been planning to make a horror game for a long time. I've come up with the story and the game engine I want to use (Unity). I want to make a PS1-style horror game (it's easier I guess), but the thing is, I don't know anything about coding. I've watched a couple of videos, but they are complicated. What should I do?What do you recommend for a newbie like me?
