unsure 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…

so this all started not too long ago, for literally no reason at all. but one day i got a random intrusive thought about harming others and it freaked me out bad. since then i’ve been non stop focusing on it and im genuinely scared that i am, or gonna end up like those sick people that have documentaries about them. i’ve never had these types of thoughts before and after me and my mom looked a lot of stuff up we think i have OCD cuz a lot of the stuff it was saying was accurate to me. to anyone in here, does this sound like OCD to you? i’ve always been a nice loving person and these thoughts freak me out so bad and make me feel like i’m a bad gross person. it got to the point i don’t even like looking at myself anymore. i just wanna go back to normal man. another thing to add, when i would explain this to my mom even though i was telling the full truth on how crappy this made me feel it felt like i was lying almost? but i know i wasn’t deep down. i’m just scared that what if i act on something or get in my head too much you know?

Hey, so I've never actually been diagnosed with OCD. I did a little bit of research, I always thought OCD was organizing things. But I'm not normal, I have this thing where I feel something isn't right. I obsess over it or if I brush my hand over something correctly then it's fixed. Or I have to do this thing on stairs, I'll walk up a few or down them because something isn't right. I read this thing on memories. I know something happened, but then I doubt myself to the point I don't know if it happened. And I think too logically in relationships. I'll put statistics on things and if they might not work out I distance myself, there's other odd things I do. My family always told me I was fine but then said things like I was messed up, and said to just ignore what I felt. Like I was making it up. I don't know what to do, I don't have a doctor currently, I was never diognosed. Is there a way to be sure I have it? Or a way to stop everything? I just want to stop everything, please and thank you. Sorry for the long post. If anyone can help, I would be so thankful.
