That's a bad way to go, making the family have to experience that. My late Mother had one of those books of important info we'd need when she passed, and made sure I knew where all her papers were - mostly consolodated into one big folder. Made things much easier, dealing with agencies, closing accounts, etc. She also had the info for the funeral/crematorium, as we had done with Dad. I have done the same, as I expect to go before my sister. It's just good common sence to help the family, when they have so much to deal with.
Take care of your family.... heal the wounds and move on.!!!! He made his choice....the easy way out.
Suicide it the chicken shit way of dealing with life! Its a permanent solution to a temporary problem, or a cowards way to quicken the end rather then being stoic and brave and showing dignity and self respect in the face of certain suffering and death! GOD has set aside a place for these people and it isn't a very nice place to be! Continued prayers Brother, and especially for Sass, he was her brother after all!
Sad day for you, with all that cleaning up and patching to do. Perhaps he did everyone a favor in the long run.
