yes it is something you do for yourself, but I dont think that makes it selfish. It does hurt your family, but i just dislike the attitude some people having as taking it as a personal insult. I have seen some people get angry at the person who did it, because now they have to "deal with it". People dont kill themselves to give others a hard time. Whatever they did it for, it was not to inconvenience others and im sure it was not an easy or light decision.
