Hyper-fixations?

I have always had a bit of a morbid curiosity. Ever since I was around…10, I’m 20 now, I’ve been OBSESSED with true crime, mysteries, serial killers, and all that dark stuff under the sun. I’ve had the largest fixation on Jack the Ripper, however. Ever since I stumbled upon a YouTuber who made an absolutely phenomenal video about him, I listen to this video about once a week, every weeks, for MONTHS now. I know it almost word for word but I keep coming back every time and each time it’s like I’m hearing it for the first time. You’d think I’d get bored of it and move on to something else, but I end up doing research, all things I already know, and get sucked back in every week.

Does anyone have any advice on how I can work on limiting this? I want to find and listen to new things, but it’s almost like a need that I have to listen to it. I just find it all so incredibly fascinating no matter how many times I listen and learn. Even when I saw pictures of the crime scenes I thought that would stop me too because of just how brutal it is, yet it doesn’t. Of course I’m always empathetic toward the victims. Is this a bad thing, is there something I can do? I’ve never been so interested in something for almost over a decade.
