The type of OCD I associate with the most is very confusing. I always feel a strong urge to check off mental checklist all throughout the day about EVERYTHING. What type of OCD is this?

I also do this, so you’re not alone here 

I’ve heard of this theme before! What we sometimes think of as OCD “types” are really just general categories of themes. Every person who has a particular theme will experience that theme differently. Yours sounds like it might be closest to the category of perfectionism/“just right” obsessions.
