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. 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.

Edit 2: I strongly recommend you don't play Carl's first, solely on the basis of it not being a strong introduction to the game. Carl's route takes a long time to get into the swing of things, and the story payoff doesn't entirely make up for it (though I still really loved this path by the end). This was apparently the first path they wrote, and cynically I think that shows a bit. Leo's path was much more of a page-turner for me throughout and I think it gives a much stronger sample of the unique Echo flavor. Leo's is the one I played years ago and there's maybe a dozen moments from this path which will never leave my brain.

I've seen people online say to do Carl->Leo->TJ->Jenna->Flynn, and with regards to Carl and Leo I'd say objectively that's probably the correct order in terms of lore unfolding, but there's only a couple of small references from Carl's route that you can notice in Leo's route, so if you're on the fence about whether you're even interested in the game at all I'd do Leo's first so you can get a proper introduction to the game's themes.
