I'm really sorry to hear that Cap! I lost my dad year before last after he was the care taker of his wife (13 years younger) go downhill from dementia. He just couldn't take the pain, or deal with his own physical problems any more so ended up 'fixing' the problem himself. I know that doesn't help you where you are emotionally right now, but I certainly can understand your pain and loss.My 94 year old Mom quit eating and drinking. She suffers from dementia, it's a sad state of living
