So I am the odd one (as usual) as the only fear I had was that it WOULDN'T happen. I was 24 and had reached the end of my rope years earlier. In the months before SRS became possible, I was seriously suicidal and surgery was the only thing that was going to keep me alive. If it didn't happen, I wasn't going to need my return airline ticket. I didn't care if I died on the OR table - at least it would be over one way or the other.
That was over 35 years ago and the only thing I was I could change would be to do it even sooner (which was not possible).
