First, can you forgive yourself for reacting as you did? Then, can you forgive your father for yelling at the news during dinner? My father died 14 years ago and I wish I could have him yelling at the news through dinner. I'd settle for us yelling at each other. Come to think of it, I'm pretty sure that I just yelled at the news throughout most of dinner. There's a lot to yell at, especially if you're an angry person like me, your father and my father. Not to make light of your discomfort; it must be hard, but you won't be living in their house forever, and you won't have him forever, or your mom to blame you for ruining dinner by reacting to him. Make a long-term plan to evolve beyond your present living arrangements, and make it happen. I'm sorry that you're in a stressful situation, and I wish you the best.
