I am so sorry for your loss. I am not in a better situation myself, my dad has been unconscious for a month now in hospital from a stroke and seizures. While i have him still physically, i don’t have him mentally and emotionally. He is pretty much in a vegetative state, hooked up to a feeding tube. He can’t talk and can’t follow any instructions and can barely open his eyes. I am sure if he knows that he would be in this state forever, he would not want to live. There is no quality of life. When this all started i used to tell him that i could not live without him (and I can’t), but if there is somehow that he knows he can’t fight anymore, i understand. I would not want him to be in pain or just to exist and have no quality of life whatsoever. I would give or do anything in this world to have him back fully even if it’s just only for one year.
