My father has had to have 2 liver resections over the past 2 weeks removing 2/3 the first time. He also buried his brother the week before. It's been a tough time for him and for someone usually caring for others, a strong leader and ambitious man, he's withdrawn and flat. He's weak and not eating much food at all. The surgeon says keep positive with him but it's like talking to a totally different person. Any advice great fully received.
