This is all sad, indeed. Suicide, and those who attempt it, is a very hard thing to get your head around. It's generally not understood.
I met a tattoo artist who took his life and he seemed to be one of the nicest people I ever met. Later, I was told he tried a few times earlier in his life and had some of the best counseling and seems to turn his life around. He had a great girlfriend and job but he succumbed to it for reasons we'll never know.
All the best,
