Alcoholic Cirrhosis

Hello. My mom is 50 yrs old and has had cirrhosis now for 7 yrs. She continues to drink wine everyday, typically a few glasses. She is 87 pnds, has ascites, spider veins on the arms, jaundice, vomits constantly, malnourished, has varcies and coagulation problems. She sleeps off and on constantly but still seems coherent! She takes a lot of meds... Spironolactone, vitamin k, fentanyl pain patches... Too much to name. My question is how long does she have? She wasjust in the ER and they sent her home saying she is fine. BP was 88/64. They always say she has months if not years left. What's the real answer? I need to know. Please help!
