You are shooting yourself in the foot to spite your face

Yes, that is what Sarah blurted out to her husband, and then she realized she had unintentionally uttered a malaphor.  As she said, “this is what sleep deprivation and being newly post partum will do to someone.”  The malaphor is a mix of “shooting yourself in the foot” (to cause yourself difficulty) and “cut off your nose to spite your face” (to hurt yourself in an attempt to hurt another).   Both phrases have to do with doing damage to oneself, literally (cutting and shooting) and figuratively.  Sarah’s malaphor contains serious damage!   Thanks to Sarah for sending this one in!
