heart attack

You are young enough to be my son so what I say is or is not maybe relative. I had triple bypass 16 months ago, 3 arteries 98 %blocked, there were NO real symtoms of heart attach coming, but just hard to do anything in the heat! Then I got the sweating off and on in the AC after some work. I was building fence!! I almost had the attach before going to the hospital.
The mental part? You are a young man so it dwells on you. I am in my twilight years, even though the surgeon said he just gave a another 10 years at minimum!
Mental!!! YOU must learn to thank God for every new day, your family and friends that YOU still have to love and cherish. YOU have to learn to put all bad thoughts out of your head. Sleep well at night. Know that whatever happens in life, you did your part to be the person you need to be. Find what you love doing, and DO it! If you don't love it, find t what you will love doing!
Like said earlier, exercise!!!!!! You have always eaten right, don,t
smoke I assume!!!!!! So continue on and exercise, and get your mind right!!!! You are the one that controls that, you alone!
Find strength in yourself, or something greater if necessary.
Don't spend the rest of or life wondering... what if or when.
Good luck!
