live in (one's) head rent-free
slang Of a person, to be a source of antipathy or exasperation to one, to the extent of becoming a frequent or continual subject of one's agitated thoughts. The term indicates that such a person is able to negatively impact one without any repercussions (with the implication that one should not allow such a person to have such an effect on them). Don't let your opponent live in your head rent-free, man. Shake it off! My mom has been living in my head rent-free for years—that's why I would deny my own wants and needs and instead do things that I thought would make her happy.
