Around 2-3 years ago, while I was doing my homework, I clicked on a creepypasta story on YouTube and I was like: "I love horror so how bad can this be?" Next thing I knew, I was so invested into this one story that I got fully distracted from my homework. Now that I want to hear it, however, the video is gone or maybe the title was changed so I would be appreciated if you can help me find it.

I don't remember the full details but here are some bullet points that I remember:

1. The story is about a security guard or a policeman who is doing night shift
2. There are three settings. One is next to an apartment/construction site, the other is at an abandoned hospital, and I couldn't remember the third one.
3. It ends with the guard/cop quitting the job.

Again, my memory of this story is pretty foggy so I would like to know if you guys know which story I am asking about. Thank you in advance.
