If you want more psychological horror emotional abuse, try Echo, which gets frequently compared to DDLC. It's set up like a gay furry visual novel to start with, but it's more like Night in the Woods where the paths are who you hang out with instead of who you explicitly want to "date". As the story progresses it gets extremely dark. I could only do one of the paths before I had to look up the others because I'm too much of a chicken.

Fair warning that it's a slow burn to get to the rough stuff, but the story is solid and it's humorous on the way so it's not boring.

Edit: I hadn't played Echo in a few years so I went to the wiki to refresh myself on the story and it is a lot more tightly-written and lore-heavy than I realized. Each "path" has a different story with a subset of the lore, so you need to play all of them to begin to understand the full picture. Even by playing all paths I think you'd have to be observant to connect some of the mysteries though. There's also a sequel, a prequel, and a prequel-prequel(?), which all presumably contribute to the lore. I see there's a giant Let's Play of most of it, which I think I now feel compelled to watch at some point. It would probably be less spooky to experience it with other people in control.
