Your attorney is not at fault because the court has denied your request to do it by phone. At least he put the request out there and now you need to be prepared to go to Ohio. See if you can change your day off from Wednesday to the day of the hearing. At least you'll not lose a day of pay that way. Also, you want to dress smartly, i.e., in a mutual color, and go there w/your head held high. You'll need to leave your emotions at the door and think of this as a business situation that needs to be resolved. You are going to be okay, it's nothing to get upset over.
How did things go today at work?
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.
