The other day I was talking to my dad and it sounds like he is showing signs of internal bleeding...Let me tell you the whole story...
About 9-10 months ago, my dad went in for a triple bypass and of course they do massive amounts of testing when you are there. So they found some nodules on his lungs and told him to come back in 3-6 months to see if they have grown or shrank. If they have grown, they were going to take samples to test for cancer.
My dad, being the stubborn man he is, hasn't gone in to check and see if they have grown or shrank and now he is showing signs of internal bleeding (very common in people with cancer). I have tried talking to him, but he is way too stubborn. I am just lucky that he went in for the "emergency" heart surgery. He told me when they found that most of his arteries were fully clogged he would NOT go under the knife...and with a LOT of persuading, he finally did it. I think he feels quite a bit better, but is starting to get bad again (I think it is due to the nodules that he has on his lungs).
So, now my job is to try and persuade him to go into the doctor, just to see what they look like and nothing more! I know for a fact he will NEVER do Chemo/Radiation, because he had to watch my step-sister do it for almost 5 years and lose the battle. He saw all the pain she was in, all the sickness she had, and he doesn't want to go through it. I don't really blame him, but he doesn't realize that he has a lot of people that care about him.
It has been almost 4 months since my step-sister past away, and I think a lot of his "pain/illness" may have to do with the emotional pain he is feeling after losing her. Eventhough he wasn't her father, he was the only dad she ever knew, so they had a pretty close bond, just like me and my dad used to.
-----------------------------------------------------------
That isn't really the way I wanted to start out the day, but I know that everything is in God's hands and HE is in complete control over this and every other situation.
For instance, my step-sister's family keep asking "Why God, Why?". I can honestly say that NO ONE knows why a little girl was taken from us except God. When we get to Heaven we will know exactly why that happened to her...plus I am jealous of her...she is in Heaven as we speak(that is such a comforting thought)! 
Alright, well I have some work to get done so I better get to it. I will keep you posted on my dad.
Have a great day!
