Travel safely and enjoy the time you spend w/your father and your brother and his family. I know it's not the same as going w/the family, but maybe you need some time to just relax and be away from the ever ending drama for a change.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
