I had a friend who thought suicide was a sin that sent you directly to Hell. I'm glad he did, though I disagreed with him. It kept him alive, for he was suicidal. I also stood by the bedside of an overweight man with a very bad heart. He was dying from obesity, but the process took so long it did not look like a suicide. Yet another man I knew just quit eating. Again, it took a week or so to die so it was okayed by the Church. All these people had one thing in common. They didn't like their present address and were willing to pitch in and help God relocate them.
Let me just say this. You are the temple of the LIVING God and until He exits the temple, without excuse it is too soon.
Put another way, a brain attack is just as forgivable as a heart attack. But why kill what God is animating?
