There is no such thing as an upside to congestive heart failure. It's called heart FAILURE for a reason. Eventually, the fluid will build up around your heart to the point that your heart will no longer function. Your legs will swell to the size of tree trunks. You won't be able to walk. Your legs will be so swollen, the very skin on them won't be able to stretch anymore, and will break. This will be painful. Sooner or later, because of the fluid around the heart, it will cease to function. I've seen it all too often...
