I'm glad we are here for you to share. I know you are scared. You're about to go through some significant changes, and being scared is absolutely to be expected. I don't have words to make this easier, but what I can offer is my presence... even if it is over miles and through a computer screen. I'm humbled, as a part of this community, to know that you feel safe here. When I was diagnosed, I was told, by a man I consider to be very wise, that I had little control over the cancer, but what I did have control over was me. He told me to go and make as many memories as I could, because at that time, that was the one thing I could control. The battle to defeat cancer would come in time, the time for me to make memories was right then and there...so I did. And, by the grace of God, I'm still making memories.
If your family is functional

I will pray for you and your family. For healing, strength, and for courage. I firmly believe that I'm still here because of the people that prayed for me. People often say that God won't give you more than you can handle...I think that's nonsense. God gives us stuff we can't handle all the time...it's then that we need to lean on Him. Not trying to get "preachy", just want you to know that you are prayed for...
Have a Merry Christmas, and go make some memories...
David
