It's easy to sit here with a clear head and pass judgment on whether you think suicide is selfish, cowardly or otherwise. People in that position have reached depths I hope I never visit, so obviously they aren't thinking clearly and we can't hope to understand the reasons.
I lost a friend to suicide 5 years ago and for several weeks I was asking myself if I had missed something, misread what he said or made him feel he couldn't reach out.
I still don't know the answer and probably never will.
