Aww, bless you, that's a double whammy! Yep, take it one day at a time and maybe one box at a time. It's nice to see you up and about making your vids though.
Just be careful not to overdo it.
My husband has stents, one from his first heart attack, and then he had to have two more put in last year when he had his second heart attack. You know yourself your own capabilities so take one day at a time, do as much or as little as you feel comfortable with and as long as you keep a steady pace and look after yourself the strength will follow.
