(24/f) my bf (27/m) doesn’t take care of himself and it’s making me angry

My bf has had two anxiety attacks and it keeps frustrating me.

Hear me out^
My bf had an anxiety attack last year that was really scary and turned out to be an expensive ER bill and long night.
It happened again today at the gym. It was pretty much the same paleness, blue lip, body shock symptoms.

Btw, he is very skinny and looks fine on the outside but I think the inside is not good. The only health conditions I know is his IBS and wolf Parkinson’s white. I’ve been trying to make sure eats healthier AND eats more. He is a software engineer and he barely eats anything so at the gym I think he was putting too much stress with personal trainer.

I would think as a grown man he’d want to know more about his body and want to take care of himself but it’s very frustrating because he just keeps laughing it off or doesn’t want to talk about it therefore I start getting frustrated.

I’m trying to help him because I care but he just so nonchalant about it.
I can’t help but think of possible future with him and think of a heart attack at 40 then what??

He says he’ll make an appointment with dr but I honestly don’t see him taking initiative. I’m not his mom but he’s getting mad because I’m acting like one 🤷🏻‍♀️
