i prolly have OCD and im scared (pls read if u can)

um i am on the way to get tested for ocd. im scared. i don't want to. but i really am paranoid all the time. to the point that i can't hide it anymore. im terrified of even eating meat. terrified out of my wits that its human meat or something. and i check every corner of every room to ensure there's no intruder and check the floor before i step to ensure i won't step on a tripwire and set off some machete flying towards me on a rope from the ceiling. i know at first there's not an intruder but then my brain just starts frantically justifying it and all of a sudden there must be an intruder. the fear mostly goes away, but then theres the always lingering fear of sudden running footsteps towards me too fast for me to even realize. it would happen, then i would be dead. the fear's there all the time. even when there's someone with me, i catch myself inspecting corners and closets and the space behind the door. same with entering any room, really, no matter if there's other people in there. in broad daylight, around others. i feel like im being watched. not in the hyperbolic way of showing paranoia, but i legit feel eyes on me. it happened in the basement yesterday, while i was doing laundry. broad daylight. not alone in the house. it was palpable and i still think i was being watched. im still angry i didn't think to look at the windows. i don't know what to do. i don't want to go to the psych ward like my parents are discussing. they think im wearing headphones, but im too paranoid to cover both my ears. what do i do?
