I smacked my 10yo son tonight for lying and sneaking. I got completely out of control and slapped him and his glasses flew off his head. The frames were bent. I apologized to him later and hugged him hard and told him I loved him, because I do. I haven’t done that in a long time, like over a year. But I’m so ashamed and hate myself for not being able to control my temper. I don’t behave like this with his sister. What’s wrong with me?
