Hi, I'm 17. My Mother has advanced heart failure and has had it for the last few years. When I google the disease it says that it's often the case that patients with AHF die within 5 years, I'm scared in case my mum suddenly goes, i want her to last as long as possible to see me grow up. I sometimes argue with her and I wish I didn't, I always feel terrible because i love her incredibly. Any advice on how to cope?
