question: My girlfriend has very recently been diagnosed with CHF. Obviously, it's been hard for me to cope with. She says she's dying and wont live past 40. This scares me, of course. But how long, genuinely, does she have left? She's only 13 (I'm 14!), and is otherwise reasonably fit and more than willing to make adequate lifestyle changes. She has started taking her medication today I believe. So, considering her young age, good health, and if she made lifestyle changes... How long would you expect her to live for?
