Not sure if I have OCD

i’ve been dealing with this “thing” since i was 15. (i’m 23 now) if i have a bad memory that i have done when i was really young or just an intrusive thought i feel like i need to tell my mom or boyfriend. it’s been on and off ever since but since January hit it’s been an everyday thing about the littlest things. mostly about my relationship. an example is i was talking to someone random at my job and we were talking about taxes and when im in deep thought or just thinking i do a thing where i bite my lip (not in the sexual way) and i had a thought when it happened “was that sexual?” and i felt like i did something wrong and i went for a while thinking that until i told my boyfriend about it. or like my ex’s face has popped up in my head in the most inappropriate times and i feel the need that i have to tell him. (my ex was not a good person) i feel like im a prisoner in my head everyday, trying to justify thoughts or remind myself that its just a thought. i didnt know that this was or could be a form of ocd. it runs in my family but i’ve just never considered it being this. i always called it anxiety or depression but i always felt like it is more than that.

I’m not too sure where to begin so some stuff may be a bit scattered. I’d like to start with the fact that I’m not sure if I just have anxiety or if it is actually OCD. I’ve been dealing with these intrusive thoughts for as long as I can remember. TRIGGER WARNING NEXT PARAGRAPH Stuff like “what if my teacher just raped me in the middle of class” or “what if I pulled all my veins at.” Those are some of the more graphic and violent things but I do get lesser things like “what if I imagined that whole conversation” when I know for a fact I did experience that exact memory/conversation. I don’t like these thoughts and I don’t ever want to think them. If anyone has any advice it would be greatly appreciated. I’m only 16 and I want to be sure about this stuff before I ask my parents to get me diagnosed.

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?
