I think I have slender sickness, from a fictional child murder. Please, I need answers

I have been paranoid since I got home from my camping trip in Pennsylvania cherry spings. Ever since I been have terrible nightmires and just yesterday I through up blood when i was recording as a attempt to catch whatever is stalking me. Yes, freakin' slenderman. Showed up right in the door frame of my house. Here is a link to my channel 6O studios. It has the video and you guys can try to help me, that is if I am even still alive... -Noah N
