prey on (one's) mind

To cause someone a lot of worry, concern, or anxiety, especially for a long period of time. I know that money issues have been preying on his mind ever since the company began issuing pay cuts. I really acted like a jerk on Friday night, and it's been preying on my mind all weekend long.
