Ebbie, that's what my dad said when my mom's favourite brother killed himself from too many years of shrapnel pain near his heart and alcoholism. My dad was not religious, but he was spiritual and he just said he could understand Uncle Howard not wanting to live another in such pain and it was his right to check out.
Villan, I hope you can find some kind of peace in all of this. I used to work as an aide, years and years ago, in a nursing home where people were left to die of neglect, disease, etc. It was not easy to see and I remember we girls sitting around on our breaks talking about how we wanted it to be if we ever were in that situation; a quick, painless, easy way out of the suffering.
