I'm so glad to hear it is contained! I wanted to send you my best wishes. My stepdad, who has been a part of the family for over 20 years, was in remission when I got engaged, but a week before the wedding we found out that it was back and spread throughout his body. We always knew the odds weren't good for his kind of cancer (esophageal) but we had hoped for the best. It was a real blow, but the process brought us together. I couldn't be there with them, but I got my mom on Skype and we talked every day. I was able to support her and talk to him before he died 2.5 months later. It was a real blessing in my life.
I am so glad to hear that things sound much better for you. Do keep your passport up, but I'm sure your dad would want you to be happy and have a good life. How great that you get to see him soon. I'm sure it will be a special time for all of you.
