I don't mean to sound insensitive, I'm just curious. But a guy on my course at University killed himself a couple of months ago. His housemate found him dead after he'd ODed. It was all quite sad, but what I found strange was that he'd actually dropped out of University about 6 months previously but had been pretending to his friends and family that he was still going. I know he must have been extremely depressed, but it just makes me wonder why he kept pretending for so long?
