Flench, I am so sorry for your Loss.
I can tell you that it will get easier as time passes. You will always remember and miss your Dad, but it will get easier to carry on. I am just now finding the "new normal" since my Dad's passing, so I speak from the heart.
It will get easier.
I am glad you were able to be there...Dads are pretty special people, it seems they never really do stop teaching us about ourselves.
My condolences, and a heartfelt <<S>> to your Dad.
