"Suicide for me is one of the most tragic events on the planet. Not just a waste of life but how could the person possibly not see that he/she would get over the problem eventually, that there are people who are concerned for them and will do everything possible to help? That's the real tragedy."
Suicide is issue that is very little debated, but it affects so many families. Many times, it solved permanently temporary issues. However, not all suicides are the same, there is also a deep cultural context (some societies are prone to high level suicides like East Asia, Eastern Europe, and Scandinavia). For many people it was a way to end pain/illness and leave a world with dignity. I had a good, close friend who chose this path. He had a renal disease that was causing him unbelievable pain and at the end he was disabled on dialysis machine. Before his suicide he wrote me very nice long letter, his farewell, and ended his life. His girlfriend told me that he was in so much pain that his suicide was liberation for him. He was no more suffering.
