I don't know how to open up to my friends I have brain aneurysm

I found this out long ago, only one friend knows it and I got it from too much stress and emotional overloads also like something called like stress cardiomyopathy which is usually for the heart but idk. It got worse during my last attempt like on January - February and it felt really shitty. I want to talk to my friends and my lover about it. I think I'm genuinely just gonna die soon which is a shame cus now I want to live lol. I don't know how to break it to them that I'm gonna essentially like die.
