Communicator, the drug issue might be very relevant, though just adding to the holes or giving the final kick. As they found drugs in his home, would be interesting which one. Big danger if psychotic people are missdiagnosed with "depression" ! Recepy for disaster. Once I had a "low mood" period , I simply had a hidden infection for a longer time as it turned out later. Can't remember the drug the doc gave me " just try this boy" ...
No suicide thoughts but I felt becoming completely disconnected to the world and myself. I stopped immediately and went to a different doctor who found the real issue.
