(((((Siren)))) I am so sorry! However, I'm glad you were able to be there with your father at the end. May you find peace in the days ahead.
Siren, I too am sorry as this is the way it happened with my mother. It has been 3 weeks now since they removed her from the ventilator and I know exactly what you are going through, and feeling. It was truely traumatizing to see the last days in that state and I too take comfort in knowing she is in a better place. Although I am not that much ahead of you in terms with coming to deal with losing a parent I just have to believe there are better days ahead.
