My mom had rheumatic fever at around 12, then again around 21. The doctors told her she wouldn't live long because of the damage it had done to her heart and organs. Same as you she set about living. She traveled, worked hard and then blew all her money. She got a big surprise in her 40's she wasn't dead and she was pregnant.
She taught me the same lessons as your dad, live, play and honor every minute of the day. My best to you and the challenges you have turned into an epic tale.
