ocd in everyday life to close friends

I had to use a pseudonym and such to join this app in the first place. If I interact with OCD content outside of here it has to be anonymous or very very minimal without any details of what I go through. I consistently deal with shame and even when talking about my OCD with friends/family I become embarrassed and ashamed, fearful of what they might think. I am like this in more cases too. I am a very private person: I use anonymous modes on almost anything, I never post my face unless the account is completely private, I never share my name online, etc. One time I scrubbed a 5+ year old account of any photos of myself or mentions of my name because I was so afraid. It’s been getting easier but that toxic shame is still triggered sometimes especially if I think someone may find out who I am. It is hard to get over especially since I’ve been treated horribly in the past.

if so, at what point? and how much do you explain? are there sources you like to use that might explain to them what it actually is?

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.
