Obsessive-compulsive disorder

“Pure O” is also a thing.

“If I do not visualize and mentally play through my partner dying in a car accident on the way home, repeatedly ruminating on this possibility, then that accident will happen. Even though this is an irrational thought, the fact that this thought came up means that if I don’t do this and he dies than it will be entirely my fault.”

Can confirm. OCD tendencies and I'm a total slob

I remember my school psychiatrist saying that I might have OCD, then I chuckled and said "Yeah, have you seen my room?".

Turns out she was spot on lol. Tbf I knew what intrusive thoughts were, I just didn't have a word for it.

See also Obsessive Compulsive Personality Disorder, which is not the same, probably should be renamed, but actually encompasses a good amount of what pop culture calls "OCD"
