My heart is heavy and I'm having trouble carrying it.

My brother going to Iraq worries me. I'm afraid he will die because he is going there for a top-secret mission on his own. He was taking a test and a 3-star general came in and pulled him out of it. The general gave him the orders that he was supposed to go to Iraq for 6-months by himself and he was not to disclose any further information until he arrived in Iraq. He is supposed to leave tomorrow which is my birthday.
