how do i know if i have OCD?

Have you ever felt the need to hide knives because you’re scared someone might hurt you while you’re sleeping? Or have your thoughts ever tried to convince you that you have feelings for your family members? Maybe you feel like you need to tell your parents to “drive safe” every time they go somewhere, believing that it will prevent them from crashing, or that something bad will happen if you don’t. These are things I’ve experienced, but they didn’t last long, and because of that, I’m unsure if I actually have OCD, as these thoughts don’t happen frequently. I’m 17, so maybe it’s still developing, but I’m not sure. At one point, I even thought I might be a psychopath and would become a serial killer (i was analyzing my past and feelings but it went away quickly) When I was a kid, I was also scared I had a tumor and constantly needed reassurance from my parents that everything is okay, but it wasn’t as intense. Recently, I’ve been scared that ghosts would come or that a demon would possess me, or that if i open my eyes i will se my dead uncle (i was 16😂) which kept me from sleeping. Are these signs of OCD? Should I consider getting treatment? About three months ago, I had my first big obsession about possibly having OCD itself (i was scared of going crazy, of feeling like this forever, of not being perfect, of not having control), and now I’ve been struggling with HOCD for three months. But I’m scared that I don’t even have OCD, and that these thoughts might be true. It’s funny because just a few months ago, I was terrified of having OCD, but now I feel like I want to have it. I think a traumatic experience with weed might have made my OCD worse, but I’m not sure. What do you think? I also found out that my mom is also hiding knifes and that she was also obsession over sickness…

man these few weeks have been so hard. i’m in the process of getting diagnosed with ocd, im almost positive i have it because everything on here relates to me on an insane level. but im just so scared dude. these thoughts of me harming someone are so scary and im so scared im gonna eventually act on them and i know i never want to but its still so scary. like sometimes when i talk to my mom about it i think in the back of my head “you know you want to” when i dont, and it makes me think or gets me scared that i do. these thoughts literally just happened out of nowhere and it messes me up so bad my literal perspective on life in general is just messed up. like i view life as its more common to be a bad person and its rare/hard to be good. can someone please just pray for me or just wish me better days. i dont even like looking at myself anymore and im scared i give off creepy vibes to myself or others now, this sucks so much

i haven’t been diagnosed with ocd but I have anxiety about harming other people/family members and it’s like urges and im scared I actually want to do it? I don’t think I’ve ever been violent as a kid (im 21 now) and the intrusive thoughts don’t go away so im just stuck all day everyday for the past few weeks just thinking and being scared about it and im having all these weird emotions like being irritated and angry I don’t want to hurt people I don’t think idk why my mind is making me think I do I’ve had intrusive thoughts before that I could brush away sure it took like a day or two but this one is different it doesn’t go away and leaves me with the worst fear imaginable and nothing I look up that should be giving me relief is giving me relief + I feel like im not in control of my body and that im just gonna lose it and act on these thoughts it’s just all on a loop and im not sure how im supposed to live the rest of my life when im in constant fear of my self
