Bad scene

Had a huge blowout with the wife. We went to pick up Sarah from her week away at camp. Everyone is happy and Cathy does something innocent and for some reason I found it intolerable and got upset. Cathy unhappy with me driving angry made a comment and I blew up worse and ended up parking the car and started to walk home in the rain. Made a complete ass of myself in front of Cathy and 3 of the kids. I feel horrible. How could I have been that way? There was no good in it and my chest still feels absolutely hollow inside. I question whether or not my heart beats. Of course to add insult to injury was the power cut off notice when we got home.
