Welcome to the Hep forum, sis. So sorry to hear your sister is so very ill. Read Ziff's thread here:
www.healingwell.com/community/default.aspx?f=25&m=3293465 I am sure this will give you some hope, but also let you know that there really is no way to know how long someone with cirrhosis has let to live, nor how difficult the journey might be.
My husband has cirrhosis from a virus....Hep C... for over 10 years. He likely had this for decades before being diagnosed in a routine physical. He now is on a liver transplant list.
I hope Ziff's thread gives you some hope. We care. You are welcome here. Big Hugs
