I hate that so many people make this blanket statement of "suicide is never the answer". Nothing is written in stone, there are exceptions to every rule. I strongly believe that if somebody is in overwhelming suffering that will have no resolution before death, they should have the right to go out on their own terms. In some ways I think it would be better for the soul to choose to leave that existence behind, rather than build up a karma based on extreme pain before finally having your life ripped from you in the end.
