Almost Gone

So here I am a few days from leaving the USA to go to a country to fight for freedom, I have had trouble sleeping the last couple nights. I'm not sure if its nerves or something but it sucks. I lay awake thinking about how I have been as a father and a husband! With me leaving and putting my family in this position to survive without me there, and putting my wife, mother, father and siblings in a worry for 9-12 months every 2-4 years because I am serving my country. I think about all my friends that are not in the military and think how nice is it to be there everyday and never miss out on anything.
