Getting closer to d-day

As the day of my departure and arrival at the PCT draws closer, I get more nervous. I know thi is my last shot. I only have one more chance to do this. To be honest, I an almost scared. Very few times in my life am I truely scared. But this is a little nerve racking. I feel that I am more ready than I've ever been, but at the same time, I've grown comfortable with the little life I've led in the past year, and I know that I am going into uncertainty and inconvience, pain, and weariness. I think I need it though. Maybe I can find that peace I've been searching for, for so many years. Or maybe I'll just quit and go back to my old job and be miserable. Whatever happens I know that I have to dig deep. I have to find that drive I once had and push harder than I've had to in my civilian life. My parents do not approve of what I am doing of course. My dad especially, but I feel I need to do this. I haven't felt the need to get their approval in years it really doesn't matter how they feel about this. But I need to do it.
