I'm sorry to hear about your friend, it is such a shame to hear about a young man unable to cope and then kill himself.
I went to pioneer school with a lovely man and he later began to ask questions about the 'truth' and because he felt so bad and alienated he eventually fell into a deep depression and this led him to throw himself off a high rised building, he was just 25. He was an extremely loving son and husband but he couldn't cope, we all tried to help him but we couldn't....
