i know how awful it is to lose a parent. Just know that we are all here for you and that things will get better eventually, though of course never over. It's been 6 years since my mom passed and I still burst into tears out of nowhere and without a logical reason.
I am so sorry about the loss of your father. It really is a wonderful thing to have shared a moment with him at the end... People involved in hospice have a special place in heaven I believe.
