obsessive person

Jamil admitted that anorexia had made her "an exhausted, boring, navel-gazing obsessive person" in her teens and early 20s.

“Tony is an intense and obsessive person,” said Andrew Munday, DoorDash’s former head of operations.

“I’m a pretty obsessive person, especially when it’s something for me, and I’m extremely meticulous — so if you combine all those, it creates a great property, but it drives a lot of people crazy, costs a lot of money and takes a lot of time.”

“I’m a very obsessive person, so one poster became every poster,” Mr. Kraft said.

Presumably by anorak he did not mean a hooded waterproof jacket, but the British slang word that the Oxford Dictionaries defines as “a studious or obsessive person with unfashionable and largely solitary interests.”
