Wow... I am so sorry. This disease is so nasty and my dad (nor your own) deserved it. I'm glad to hear he was such a strength in your life, I can relate. Keep any and all memories alive. That's what I do each and every day. It's by far the hardest death I've had to go through. I hope they find a cure or better treatment one day... there's many strong people on here going through similar situations. I wish everyone the best of luck.
