It is an interesting point that Carnelian raises, and it is certainly not a conscious decision on my part (not to post on emotional issues). Although I am the sort that has always cried at sad things in movies etc, I consider myself a very pragmatic person and my main point in posting things on this forum is to post positive messages about my experience of heart surgery. I don't have any medical knowledge, and I have only been through it once (thankfully!) so those comments are limited in their nature. But I was told that many people go through depression after major surgery and I see many posts from people with significant anxiety before their operation, so I hope my amateur contributions have some use in allaying fears. (I had no depression myself)
Needless to say, friends and family worried a lot about me before the surgery, and I had a lot of visitors whilst in hospital. But to be honest, once I came out of hospital it seemed as if the view was "he has survived, he is ok now", and I had almost no visitors at home apart from a friend who came to stay and help whilst I was in the early days of recovery! (I am single and live alone). Actually I think that was fine - I wanted peace and quiet, to rest a lot and sleep whenever I wanted, which I did and I am sure aided recovery.
I too find the use of abbreviations annoying, and frequently have to Google them. And if you think they are liberally used here you should try a pacemaker site!
