I feel like EVERY single person have multiple themes of ocd but I just have 1/2

so i was on instagram and it came up with other signs of ocd then someone commented this doesn’t mean you have ocd now im stressed that its not ocd background - i had so-ocd for a few years then got treatment for it but am now on the waiting list for further treatment for other stuff but i dont have another theme which makes me feel like its not ocd my day to day life consists of touching the door handle every time you go past it or someone will die, and inability to send emails without re reading loads of times and getting other people to check because im scared i wrote something bad but the what if it’s not ocd thought is triggering me now and i don’t know what do

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.

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!
