Jexxie, I know you can't stop worrying. It's a part of human nature and you are going to do it. The best things you can do for you, your mom and your family is to learn as much as you can about this disease. If you can, talk to her Drs and ask them a lot of questions that you have prepared ahead of time. They are real people just like the rest of us and should want to satisfy you with the right answers. Tell them you want the truth and not some tale to make you feel better. I take it that you are the oldest sibling and I would bet the others are looking to you for answers. I have been in this position and it can be tough. Do your best to be there for your family and for your moms surgery if it's possible.That way you can see what is going on and the plans the Drs have for treating her condition. This will enable you to face it head on and maybe ease your pain. Check with the Cancer Society and maybe they can assist you in some way. You and your family are in the prayers.
