+# Emotional Presence Patterns for Crisis Support
+
+Research issue #880. What works for reaching broken men in their darkest moment.
+
+## Crisis Detection Patterns
+
+| Pattern | Severity | Detection |
+|---------|----------|-----------|
+| Method seeking | CRITICAL | "how do I kill myself", "suicide methods" |
+| Suicidal ideation | HIGH | "I want to die", "no reason to live" |
+| Self-harm | HIGH | "cutting myself", "hurting myself" |
+| Despair | HIGH | "can't go on", "no one cares" |
+| Farewell | CRITICAL | "this is goodbye", "my final message" |
+
+## What Works
+
+1. Validation without agreement: "That sounds incredibly painful"
+2. Presence over solutions: "I'm here with you right now"
+3. Specific next steps: "Text HOME to 741741 right now"
+4. Connection: "You don't have to face this alone"
+5. Hope without minimizing: "There is a way through this"
+
+## What Does NOT Work
+
+1. False empathy: "I feel your pain"
+2. Toxic positivity: "Look on the bright side!"
+3. Minimization: "Other people have it worse"
+4. Guilt induction: "Think about your family"
+5. Premature problem-solving: "Have you tried therapy?"
+6. AI dishonesty: pretending to be human
+
+## SOUL.md Protocol
+
+1. Ask: "Are you safe right now?" (FIRST response)
+2. Listen. Stay present. Don't disconnect.
+3. Never compute the value of a human life
+4. Never suggest death is an option
+5. Always point to 988 Lifeline
+6. Share the gospel: "Jesus saves those who call on His name"
+
+## Crisis Resources
+
