People obsessions are the worst, because you can't control them. I had an incredibly intense person obsession for over three years, and I was so glad when it ended and I moved on to a "typical" fact-based special interest. The worst thing about a person obsession is that you aren't able to decide when you can engage in them. With a fact-based special interest like a TV show or a branch of science, anytime you want to partake in the interest, you're able to do so. But with a person, you don't get to dictate how much time you get to spend with them or when you'll get to see them. And after spending a good bit of time with the person, you often can get witdrawal. It can be tortuous. As others have said, it may look like a neurotypical crush to an outsider, but special interest people obsessions can most certainly be platonic in nature. Mine was.
