It's starting to sink in

I keep having in my head that I'm going to Africa in a matter of months, but it's honestly really just starting to sink in. Right now I'm watching a TV program where the main character leaves for Africa and he's saying goodbye to all of this friends and family, and I'm crying because I can't help but think of how I'm going to be doing the exact same thing in 8 1/2 months. I'm not having doubts because I know I'm able to rest on the peace God has given me about this decision, but I still have my moments of having a hard time.
