Going Tommorrow

It's 12:40 and my flight leaves tomorrow morning I cant sleep. I'm wondering whether I'm doing the right thing. I am going to miss my graduation leaving behind everyone and going on an adventure.
I'm really worried about the flight, 21 hours sounds like hell to me. I'm scared about the first night alone in Sydney 15,000 miles from home. I must be made. Either my next journal will be very happy as I enjoy my adventure goes well or depressed alone in a foreign land.

Australia here I come!
