I went to University to be a social worker for children of cancer cause my step sister had it, but when I went into the janeway I got sick from the smell of death. So then I decided to be a social worker for rape victims and addicts.  Dropped out though to get married for the first time! 
I grew up with family in AA and the 12 step programs and had a sponsor that thought he was a failure in his success and killed himself. But I remember going to the bar one night on a big bender and seeing him there after he died. I wasn't the only one that thought they saw him that night. Freaked me out and I still miss him dearly, he was on the straight road but wasn't taking it one day at a time, he was thinking way to far ahead of himself. But he was doing great just had a slip 

 Still blame myself that I didn't see his slip and help him the way he helped me all those times.
Another friend thought his girlfriend was leaving him and up to the cabin he hauled out a shotgun and killed himself in front of his girlfriend.  It turned out she was pregnant with twins and didn't know how to tell me. It was a hard year in school. 
People who do this don't realize just what they are leaving behind. I agree it is selfish, they don't seem to think about what they are doing to the family and friends that stood behind them and tried to help them out.
 
Sorry drunk right now and that hit hard. Seems like yesterday and it was over 15 years ago.
