I’m sure you did fine.
I did the same when my dad passed, although he was nowhere near fit. Same result.
Sometimes there’s just too much damage done to the heart in the attack.
You tried and that’s what is important. Please. Don’t beat yourself up over something you had no control over.
My condolences. It’s a hard thing to live with.
Yes. I’m getting better at not beating myself up. Took almost 5 years to get a grip on that.
