I am so sorry to hear what you & Rob are going thru, it is so unfair. I can't offer any help, other than prayers for you both on the the treatment issues. You mentioned that your sister and your children are helping and that you felt it should be parents helping their children..... My mom died of small cell lung cancer this past year an the last 2 years of her life she was completely broke. Rick & I were able to help my mom & step father out financially, Now that mom is gone I have no regretts and if I could do it over again I would give her more. Please don't feel bad about your children helping you, You and Rob sound like wonderful people and I am sure your children feel honored to help in anyway they can. Hang in there & feel the prayers and warm wishes coming your way.
