Suicide loss carries a grief that most people do not know how to stand next to. The death is sudden, often without warning, and it generates a specific kind of guilt that ordinary grief does not — the relentless rehearsal of what you might have said or done. If you are carrying that, it is worth naming directly: the responsibility for another person's death does not belong to you. You did not make this choice. They did, in a moment of pain that eclipsed everything else. That is not a theological claim about their destination. It is simply true about yours.
The question of where someone who died by suicide goes is one that Christians have argued about for centuries. The older tradition treated it as a categorical sin that determined one's eternal state. Most serious theologians today recognize that judgment belongs entirely to God, who alone knows the depth of suffering that preceded the moment, and who is described throughout Scripture as one who looks at the heart and not merely the act. Romans 8:38–39 does not contain a footnote. Nothing in all creation, Paul writes — and then he lists categories specifically designed to be exhaustive — shall be able to separate us from the love of God. That is not a promise about how a person lived. It is a statement about what love is.
Lament is an appropriate, biblical, and holy response to what you are going through. Psalm 88 is the darkest psalm in the canon — it ends with the word "darkness." No resolution, no turn toward praise, no morning after the night. God preserved it. He does not need your grief to resolve before he can be with you in it.
