I'll tag on more prayers for you and your family during this time. My dad went through colon cancer, and he went through the same surgery. He's been cancer free for 5 years and he still has to get testing.
My advice I give to you, is to keep praying. Cancer is an ugly disease, but at the same time you're living through this obstacle. Please don't concentrate on this disease as dying.
As a daughter to a father, if you're scared, we're scared. If you feel like you are dying, we feel like you are giving up. When your father is your rock, it is miserable to see him (or anyone) have to face what you are right now. But, my father has always taught me to think positive, be strong for my mom and sisters, and to enjoy life. Enjoy living.
Some people are given 2 weeks, some people are taken at 2 years old. Remember to enjoy every breathe you take. Even when you are scared and want to curse this email. People are praying for you, even complete strangers. But the power of your own positive thinking will take you places you never thought you could get to.
They gave my uncle 2 months with brain/liver cancer. He is still alive, 12 years later. They gave my father the title of colon cancer, he went through the surgery, recovery, chemo and is still in testing each month. We don't know what lies ahead, but we don't live as if he's dying, we take each day as a gift and just ask God for one more at a time.
Don't feel like you're alone.
