I agree. This is very traumatic. Talking about it here or with a therapist will help. I remember caring for my neighbor who was diabetic and had no one to help him all the way up until his death. I was in my early twenties and my wife and I lived away from our parents. We had no idea what we were doing and every time I heard an ambulance I would experience PTSD triggers for at least a year. Talk it out. Sorry for your loss.
