Hey brother - hope you're not feeling too down.
You kinda goaded that answer out of the doctor, he probably channeled his lawyer to deliver that response.
Your toughing it out phase kinda ended when you told your daughter and went to the doctor though, it's a good thing bro.
You also had already started prepping by making heart related lifestyle changes, ditching kratom, etc and this event has already taken place and now it's too late to go back and try ignore it.
Though ah, I would be too
Things might get busy for a while. They'll probably heavily question your diet too. Honestly the heart is my biggest concern. All the dead lifters I know personally died from cardiac events.
I think this is probably one of the times you should heavily rely on your daughter. She's not going to stear you wrong and she surely knows more than us.
I'm around anytime if you need to chat bro.
