You never know how much you are affecting somebody by being rude and nasty..people slam these people for not being tough enough to solve their own problems..but, you REALLY don't know the torment of living depressed. You just don't, don't pretend like you know exactly what you would do if you were in the other person's shoes.
I had a cousin that blew himself away a few years ago. He was very smart and seemed to be happy according to everyone who knew him, but he was not. On the day he killed himself, he tried to reach out to his mother, both through verbal and written communication. She did not pay attention to him, so he simply left another note saying "Im sorry, I tried". He went into his room and shot himself in the head.
I will never understand what it was like for him to wake up everyday and live in this world...and I won't just him for taking the easy way out.
