I'm sorry that you are feeling sad about the trip right now.

Is this how you see it? You didn't want to go at all. You gave in and agreed to go. Then you made other arrangements that perhaps lessened, but did not overcome, the damage of giving in.

You'd still rather not go, especially since now you know that friends from high school that you thought you would see, that would have helped you lessen the damage, won't be there after all.

Can you see the arrangements you made to lessen the damage as being good, significant, positive steps for you? Or do you only see them as minor in comparison to the fact of going home at all?
