I read that yesterday, and it was definitely moving. I cannot imagine what losing a son would be like, and especially to suicide.
My father and brother both committed suicide, and my brother's was the worst day of my life. Suicide leaves you asking so many questions, and I still often wonder if there was anything I could have done to prevent his.
My father was never in my life, so it did not really affect me at the time, but I now sometimes wonder what it would be like if he was still alive. Would we have a relationship? What would he be like to my kids? Etc.?
