I am so sorry to hear about the sudden loss of your father. I pray that you and your family will get through this very painful time. I dont know if you are religious or not, but I find great comfort in what the bible says that one day soon, there will be no more pain, nor outcry, nor tears (Rev 21:3,4) so no one will ever suffer anymore, and it mentions how even dead loved ones have a hope to live again and be re-united with their loved ones (John 5;28, 29) in paradisaic conditions right here on this earth (Psalms 37:9-11,29). This will happen in the near future, the bible promises. That is what helps me in coping with my grandmother's terminal condition, and will sustain me after she is gone .
Take care of yourself , and all the best to you and your family.
