I can feel your fear just by rading your post. As you know, you cannot let fear control your life. You are who you are. You can make substantial changes, but inwardly you are you.
It's amazing that we are both warriors, but this type of thing tears us up. I get the "not making W. angry thing". You've been with me for a while. I had a good friend who flew MEDEVACS in Iraq. His W. wanted out, and he had to give up an aviation command, because he was so torn up. Another warrior.
I'm thinking that after a year in Iraq, when I come home, I'll want to live the remainder of my life trying to be as happy as possible. I'm 51, and a year and a half out of my life is a great proportion of what I have left. It's not as easy as giving a year up at age 24.
I'm glad things are positive for you. I wish you nothing but peace, tranquility and success.
