It's Twine, and it's short. I'm not sure what it is about Twine, but most Twine authors seem to like going for some sort of highly-rarefied, artistic take on troubled aspects of the human condition. Here, we're looking at something about obsession, or obsessive-compulsive disorder, and the way it gets in the way of relationships. There's nothing to change: it's an exploration piece, in which we poke at all the moving parts for a fuller understanding of what's going on and why our hero feels the way they do ... what it's like to be them.

I'm torn, though, as to whether I'd have liked to explore a bit further, or if I'd hate to spend any more time in this headspace.

I can't speak to its authenticity, not having myself suffered from OCD (near as I can tell, anyway) but it sounds plausible enough; and plausibility is everything when the goal is the exploration of a headspace. So I'll say the writing is well-done. I think I'd have liked to have explore a bit further ... though I also suspect that I'd hate to spend more time than I have to in this particular headspace.

I think it's a bit like having a slice of leftover wedding cake for breakfast. This cake is part of something bigger than itself ... it's a piece of someone's life. But it's also kind of sad now that it's the morning after, and though you secretly want more, you're pretty sure you'd get sick from too much fondant icing. But someone's got to eat it, otherwise it'll just sit there in the fridge asking you why you haven't done something about it yet why why WHY? Better just wash it down with some iced tea and get on with your life.
