help with end of life decision

My mom died almost a year ago. I am relatively young and shouldn't have lost her. They caught her cancer too late and it was already metastatic, meaning it had already spread. Her 5 year survival chances were like 5% with 50% at 1 year. She lasted 6 months. In the end she had huge tumors growing around her neck, had difficulty breathing, and couldn't eat or even really drink. She was terrified. I was administering medical cannabis until the final few weeks and then switched to morphine that the local hospice was kind enough to provide. Her tolerance built up pretty quickly but she was in constant, debilitating, end of life pain. She kept asking for more even after I was dosing way over what she was prescribed. I gave her enough to kill an elephant and took her oxygen off, at her request. She repeated "I love you" over and over again. Hours later she went into mandibular breathing and died that night. This was after 15 days with no food and 5 days with no water. I don't know if I killed her but I don't regret it if I did. I am not in a legal assisted suicide state.

My opinion, end of life care is end of life care. I did what was necessary to ensure the woman that birthed me didn't die terrified and in pain. My eyes are tearing up writing this response and it's the first time I've ever spoken about it but, from someone who's been there, do whatever you have to do to keep him comfortable and think no more of it.
