I’ve OCD, if that counts (not self diagnosed. I’ve a proper diagnosis from a psychologist and was on prescripted meds for a long time).
Most people think you’re just supposed to wash hands too often, or arrange things symmetrically, or just be a cleanliness and symmetry freak in general. But that’s far from true.
OCD is of many types. The one where you are a cleanliness freak is also valid if you’ve it to an extreme level. Unfortunately, I don’t have that. I’ve the less popular one with random “what if” intrusive thoughts that also have their own solid almost traums inducing anxiety to go with them. Fun stuff.
