Have cardiomyopathy with heart failure. I’m lost feeling like this.

EKG with a LBBB sent me to a cardio. Echo read 34% EF, Mild to severe systolic function and global hypokensis. Angio came out clean for the most part. Currently on Entresto and Carvedilol. Really at a loss on how to live my life. Can’t work out anymore, always tired and always dizzy. Only thing that gets me is I’m a single dad who raised my daughter and we are extremely close. I’ve been trying to adhere to a more strict diet, don’t drink alcohol or smoke. Speaking realistically, how does this affect my mortality? I sweat like a whore in church, can’t shake the tiredness, pee like a racehorse. This is just crazy. Sorry, I guess I just needed to vent.
