Freaking out

I bought a plane ticket (finally) and now I'm feeling like this is really happening and that I'm really going to go.  I have never been out of the country and I'm freaking out all of a sudden.  I have been planning this trip for what feels like my whole life and I have been fundraising for what feels like half my life.  I now have raised $13,000 and more than 90% of that I've gotten from people who really believe that I can go over there and do something great.  I hope they are right.  I am very excited about my trip and really ready to leave the country and do great things, but sometimes I worry that I'm not cut out for it.  A good friend of mine told me today that God has chosen me to do this and has clearly put a lot of investment in my ability to do it, so he's not going to put me on a plane and then suddenly abandon my cause. It's just not going to happen that way.  I also know that I have a ton of people here in the States who have my back through this no matter what.  I've gotten all 6 of my shots, and I'm ready to go.  I just need little reminders here and there, cause it's a scary thing I'm undertaking.
