Is it possible to only have one ocd theme. I’m honestly just trying to figure out what i could possibly have and seek proper help but I’m not too sure what is wrong with me is ocd rather another illness because as far as I know I’ve only ever really had one theme and it has been a problem since I was 11, I am now 17. I see everyone on here having multiple themes but I only suffer from so ocd so I’m just not too sure what to think.
