Nikorah, I would not go as far as saying everyone that has heart surgery has "extreme depression" or even depression at all. It is very much an individual thing. I have had friends, including my brother that had heart surgery & some did experience some depression after surgery. Not all of them required being put on a low dose antidepressant either. In my brother's situation & a close friend, these were highly energetic people that went 500 miles an hour every day of their life & young. Suddenly, they have surgery & they had no idea about the recovery time, it made a big impact on them. This made perfectly good sense as to why they got depressed. They did not need to be on medication long & did great.
My advice don't anticipate something that may not happen to you, too unhealthy & not productive at all. I very much mean this in a kind way too. Take care.
