Fear or Excitement?

I have always thought I was the adventurous type, however I don't know where fear makes it way into that equation. I am too young to know what percentage of risk taking is fear or if people that are truly adventurous just overlook the fear factor and brave the metaphorical fog, although they do not know what lies ahead. Am I capable of that? Can I leave my family and friends for the next 5 months without getting severely homesick? Can I be excited instead of being scared? I'll find out soon enough (I should have thought about these questions when I was applying two weeks ago). I've always wanted to do something like this, and now I have the chance, and I am finally getting what I want and I'm freaking out. But hey, I guess it's like anything in life, when you get what you really want- you never know what to do with it. When I woke up this morning the only thought in my head was " I know I have not left yet and it's still four days away however, but I'm scared."Are those the first words of a truly adventurous spirit? Even yesterday when I was supposed to hang out with someone (and it didn't work out) three million thoughts started running through my brain, I don't know how rational they were, but the largest thought was "I don't know when I will see them again". This is not the end up the world and it's not like I'm never coming back but it happened so fast and I just want to have time to do everything and see everyone. Again, I don't know if I am being dramatic or this is actually the process that comes along with taking chances and experiencing new things and fear and worrying are part of the "new adventure" care package....maybe it's too soon to tell.
