Trying hard to make Lemonade

Just as we thought we were getting a handle on my father's condition we were hit with yet another stumbling block. 
A simple nose bleed turned into the discovery of a pre-luekemic condition.
We had a Dr. appointment 2 weeks ago on Wednesday or so I thought.  I normally meet my dad at the hospital and because we are out right about lunch time I stay with him and we have lunch together and then I head on home.
Most of our appointments have been on Monday, Wednesday and Friday.  But this week they were on Monday, Thursday and Friday.  I however got it stuck in my head that we still had the  appointment on Wed and went in.  When my father did not show up at the appropriate time I re-checked my schedule that I keep on my phone and saw that I was a day early.  So I called my dad to see if he was up and about and I thought that I'd go over and visit with him for a bit and help me to run some errands if necessary.  When I called him he casually mentioned that he woke up with a nose bleed.  He doesn't get nose bleeds.  So I told him that I would be right over.
I arrived a few minutes later and although it wasn't pouring out of his nose...every time he put a handkerchief up to his nose there was about a quarter sized spot of blood.  I told him that if it didn't stop by 11:30 then we were going to call the Dr. to see what to do. 
It didn't stop and we called the Dr. and were told to go to the Emergency Room.  I called both siblings that are in town to alert them to the condition and we were where we needed to be so there wasn't much else to do except to wait for the Dr.
To make a long story short my dad was admitted for blood transfusion, platelets and a bone marrow biopsy.  He had to stay the night and we all waited together until he was released the next day.
We got the prelim results of the bone marrow biopsy which told us that he had this pre-luekemic condition. 
A new chemo regime was started and he had another nose bleed, he's had 6 or 7 sessions of platelets and 2 more blood transfusions.  Dr. told us yesterday that he needed to see a specialist and so we are off this week to Houston to M.D. Anderson. 
I'm trying very hard to make lemonade with this.  His current Dr. although very competent is just an oncologist.  At M.D. Anderson he will be meeting with a specialist of Leukemia.  He is willing to see us this week and my dad is willing to go seek treatment. 
I know that my father is going to die.  That's a fact.  I hate that but it's the truth and the sooner that I make peace with that the better I'm going to be able to cope when it happens.  What I'm having trouble with is that there are so many family "events" coming up that he really wants to be here for and because my mother isn't here to attend I would like one grandparent who was so much a part of their lives to be able to be present at these life events.  Next month we have 2 graduations....one grandchild is graduating and becoming a Dr. of Veterinary Medicine.  Then 2 weeks later another grandchild will be graduating with his BA in Teaching.  Another grandchild will be getting married in early December.  So I'm thinking positive thoughts and trying very hard to make lemonade out of the lemons that  I've been getting.
