Hey Dearth, first of you'll be fine so don't be discouraged.
Yours is a minor heart attack... I had a Cardiac Arrest 2 years ago, got stented and was lucky to survive. Then after a year I went on another procedure which they had implanted an ICD on me. On the first year I was totally depressed as I was only a shadow of a man I used to be. The biggest frustration of course is how am I gonna take care of my tanks? No more scuba diving for me... etc.
That time that I got ill, I got so many tanks running. I have been breeding discus and for people who are aware how tedious it is to keep discus is... tell me about "Daily Water Change."
But my life didn't stop there, I didn't let infirmity stop me from doing things that I love. I was lucky my wife supported me and managed to take care of everything when I was in the hospital with the help of my father in law until I had decided to let go of everything except for my 57G reef. This tank served as a therapy for me while I was recovering. In fact my Reef addiction got worsen.
All I can say is, it depends on the people that surrounds you. I always thank my wife for understanding and supporting me with all I've gone through. My father in law and my son who lift things for me when I need to as I was refrained from lifting things.
Life and reefing must go on for me... as a matter of fact I am working on my ultimate goal... "To go back home and scuba dive on one of the nicest reef in my country." I'm hoping I will be allowed to dive for less than 50 ft.
By the way I'm back working full time for almost a year now.
Stay positive!
