My Dad had the same. He went into hospital and was told it was maybe kidney stones and would be given antibiotics. 13 days later he was gone. We had no time to say things ,hug or plan anything.  After he passed I went to the outpatients appointment that had been booked for him that we were meant to go together . I found out then that it was pancreatic cancer.
I went through the motions at Christmas too for my Moms sake.  I still feel like I'm dreaming and am going to wake up.  The shock is absolutely devastating. 

Hi , I'm a new member too and this is my first post . My Dad passed away unexpectedly on the 16th December. I feel exactly the same as you have described. I simply cannot comprehend what has happened . 

Hi

New to this too. My mum passed away on 13th Nov from pancreatic cancer, she was diagnosed 5 weeks before so it was a complete shock. Christmas has been hard, but we went through the motions for the kids. Over the past few days I cant stop crying and my heart literally aches, I'm also struggling with the fact that its sinking in Im never going to see or speak to her again.

I'm so sorry for your loss. It is devastating. I'm 41 and feel like a child all over again. My dad is also struggling without her.

Hi

im so sorry for your loss losing a loved one does not get easier with age. Love for a parent is timeless. As I write this post tonight my Dad is in the final stages of his life he has fought lymphoma for 10 years but now it has caught up with him. I am heartbroken I loved him so much. He was my hero after adopting me and being so kind and caring all of my life. I don't know how I will carry on.

Hi I'm so sorry to hear that. Your Dad sounds like an amazing person and I bet he knows how very much you love him. I keep telling myself that my Dad would not have wanted me to go under ,he would have wanted me to be strong and carry on. It helps a little knowing that and from what you say I bet your Dad would want the same 

Hi

thankyou for your reply it was kind of you. My Dad passed away today and I was with him along with my Mun and sister. I felt a sense of relief Dad was no longer suffering but I am also deflated and miss him.

I'm so sorry , take some comfort that you were with him and as you say your Dad is no longer in pain. 
My heart aches ,I miss my Dad too. I'm currently sat with my Mom planning my Dads funeral. I can't believe it 

Yes we've been doing the same. I'm so sorry for you and your Mum. The only thing to do is focus on the good time you had. Take Care in this difficult time. Best Wishes
