First I will say that I am leaving on Thursday. I am going to make it, but I'll be in desparate shape.
Here is my advice: Once you have made a firm decision - DO IT - immediately.
My mistake was to not return right away. This last 6 weeks have been too horrible to describe. I had bought my ticket, made my arrangements and thought that I would put off returning as that was the thing to do (?). MISTAKE. Now I am simply a wreck, and so is everyone else around me.
