drown (one's) sorrow(s)
To attempt to forget one's troubles through the consumption of something, typically alcohol (to which the phrase originally referred). It's not healthy to just drown your sorrows every time a girl breaks up with you. Quit drinking and try to face reality. Whenever I have a hard week at work, I like to spend Friday night drowning my sorrow in pizza and ice cream.
