Brad, I can't say anything more than what everybody else has said. My heart goes out to you and yours. You and your family will be in my prayers for the coming days. I lost a daughter to cancer in 1997 and my wife of 43 years, in 2006. I know how hard it must be for you. You never get over it. The pain lessens, but is always there. Just knowing that they are in a better place is the only thing that brings some comfort. If there is anything that's within my power to do, all you have to do is ask.
As for my other children, I live with my son and daughter, her husband, and my grandson.
