I know this might be a dumb question but blcan OCD be self diagnosed? Like if symptoms make sense and you are struggling with the same things someone with ocd is dealing with too could you self diagnose yourself until you get help?

I've never seen a therapist or been diagnosed, so I went surfing through to find this community. I've seen a lot of OCD symptoms written online. Here is what I experience that I feel may be OCD. If any of you guys agrees, please let me know. I have only ever been able to call my mom by her first name. I have never been able to not do that. She tried to make me call her mom once as a kid but it felt so wrong that I started crying. Everytime I see a wet floor sign, I say "piso mojado" out loud. I have plenty of harsh intrusive thoughts, such as committing acts of violence when I see people not using their turn signals, interrupting performers at a concert. I make myself re-press on my phone alarms 10-12 times each day in the same rythym until it feels fully set to go off. Light switches get flicked off and on, I can't stand not doing it. I have to double-check everything and make myself re-look through the same drawers at work for hours. I love to write, but I never get far because I need approval from others. My head is also always filled to the brim with thoughts which has made writing and things like memory a lot harder. I can't use spoons. I can only use forks for almost everything. I can't stand them. That's all I can think of for right now. Please let me know what you guys think. Thanks!

How to know if you actually have it or if I’m just making up the symptoms? I have a lot of intrusive thoughts constantly and even have a “theme” but it really surged after I search up what I was experiencing, but then again I search up a lot of what I experience and constantly have to recheck things. My parents say I’m normal but I know I’m not, (both of my siblings have adhd) I find it immensely hard to focus from turning 17-18. Please let me know what you think l! Thanks!

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.
