Your dad is not in hell, HootOwl.
Whoever is reading this, is religious and has lost a person to suicide, don't assume this person is in hell. I will only cite this episode.
There was a woman who told St. John Vianney that she was devastated because her husband had committed suicide. She wanted to approach the great priest but his line often lasted for hours and she could not reach him. She was ready to give up and in a moment of mystical insight that only a great saint can receive, John Vianney exclaimed through the crowd, "He is saved!" The woman was incredulous so the saint repeated, stressing each word, "I tell you he is saved. "
The certainty that suicide leads to hell is an idea that comes from Augustine, it was not in the Gospels. I said this earlier in this thread. Jesus is mercy and brings the idea that God is love and a merciful Father, in strong contrast with some depictions in the old testament, and what kind of mercy would be sending to hell for eternity (!) a poor soul who was suffering so much that saw no other choice than ending it? It doesn't make any sense. And anyone saying "God is merciful but is also just" (and hence Hell) is thinking like a Pharisee. Not only that, but even the idea of _eternal_ hell comes from Augustine. Scriptures are ambivalent on this but Gehenna and Sheol are not an eternal lake of fire.
This is for the religious people. Many others here will be troubled by the problem of evil. How can a fatherly and omnipotent God subject us to so much suffering? Others simply won't be interested in religion, but this post is addressed mostly to religious people.
Of course this is not an encouragement or endorsement of suicide for religious people. I agree we need to try as much as possible and do our best. I have sympathy for anyone contemplating this, as I said many times. No judgement. We are only human. But we should try to get through this as much as we can. I know many of us here feel we got past the limit.
@Johnny Karate, I understand your good intentions and I appreciate your encouragement to hold on, as you are doing yourself, so many of us here need support, but you have to be very careful with what you write, some statements can backfire. A suicidal person needs compassion and understanding rather that be threatened to end up in hell, which might only increase her desperation.
We need all to be strong but I don't know how.
