Cirrhosis of the Liver?

Well my dad was diagnosed this 4-5 years ago but never told anyone. My mom talked to doctors and was telling us kids what the symptoms are and everything but then she was listing them and said she well im not going to tell you the last thing. I already know weakness,fatigue,loss of appetite, nausea, weight loss, abdominal pain, itching, spider-like vains, nose bleeds, bruising, swelling of the belly/ legs, jaundice and some confusion this last thing seems to be very important. i already know he doesnt have much time left so what is this bad symptom that my mom is hiding from me i mean it cant be worst than him dying......please i would really like to know and be prepared for the worst
