I'll never fully understand what leads people to committing suicide. It's a sad thing and I have had to deal with the aftermath when a family member and good friend chose that route.
The ones that are left behind not only have to deal with the surprise and pain of unexpectedly losing a loved one through death, .. which many people have to do.
But they also have to deal with the heartbreaking pain of feeling like it was somehow their fault, or that maybe there was something that they could or should have seen or done.
That is true pain, and hard to live with.
My experiences have shown me that no matter how bad it gets for me or us, or what I am going through, (miscarriages, death in family, losing a job, family health and other issues, etc.) ... no matter what is going on in my life, someone else has it worse.
