Today, I wonder, why am I here? Like many people, yesterday's anniversary of the 9/11 tragedy made me more depressed than ever. Early this morning, I went on a website that listed the names of the nearly 350 firefighters that were killed trying to save lives that day. All those brave people were true heroes. I see stories like that and it makes me angry. They should be alive, not me. I am just a waste of space who has done nothing good in this world. If I could trade my life to bring one of them back, I would.
