It happened to me bro! I know exactly how you feel. My first bit of advice is this; Get ALL of the facts before you jump to conclusions. There is no worse feeling than being in Iraq, all alone. Don't make it harder for yourself by being rash about a rumor you heard from somebodies best friend's, girlfriend, who is the second cousin to Ben Aflack.
If, after you find that the rumors are true. PM me, and I will tell you how you can get around a lot of bullshit that the military puts you through.
