A teenage boy was deer hunting 2 weeks ago with his best friend. His friend was accidentally killed by another hunter.
 
  The boy whose friend was killed experienced decreased appetite, insomnia, and inability to func-tion at his previous level in school, so his parents consulted their physician. They report that he seems obsessed with his friend's death, talking about the accident repeatedly. What is the best problem formulation? He is:
  1. Attempting to avoid dealing with his pain
  2. Feeling responsible for his friend's death
  3. Experiencing a normal grief reaction
  4. At risk for self-harm in an attempt to be with his friend
