Does anyone else feel like their theme is in their mind 24/7

I’m curious how many other people experience this! I’ve been diagnosed with severe OCD for 20 years now, about 10 years ago my little OCD brain came up with a series of words. It is saying everyone in my families name and then something negative, and then something positive. Since my brain attached to this series of words, it hasn’t stopped repeating in my mind. Like I said, it’s been 10 years, and this “phrase” is constantly repeating over and over in my head. When it’s finished, it just restarts again. My brain is constantly exhausted since it’s always talking. It’s kinda hard to word this so idk if it’ll make sense to you but let me know if this is something that you might experience as well!

Anyone else feel that when they aren’t experiencing a theme that their ocd is almost non existent. It almost makes me feel like I’ve been faking it, and also makes me feel ridiculous for obsessing over things. I feel sorry for myself :/ I know that my themes are valid and felt very real in the moment, but after I “get over” them I just can’t believe that I was obsessing over something that either wasn’t true or didn’t apply to me. I would also like to know how to prevent themes from reoccurring. Health, religion and existential OCD themes tend to take turns throughout my life, I just didn’t know that was it ocd. Trying to break the cycle.

I have read many people use the word theme in their posts. I think I know what that means as far as OCD goes but could someone please confirm me??? Thanks!
