The shock itself of losing someone young so suddenly is one of the toughest things you'll face but it will get better to deal with and you'll be an even stronger person. I'm sorry to hear about your loss sending love to you and his family and friends < 3
I am so, so sorry for your loss. It is infuriating to me that people think terrorism makes them intimidating. It is cowardice, it is stupid; problems will never be solved until peaceful conversation is made.
Forgive me if I'm being insensitive or too intrusive but are you a student at Emory U? I have a friend who goes there and also lost one of his friends yesterday in one of the attacks (I know two from Emory passed in one of the attacks).
