Oh, kat ol' kid...
A few years, decades now, back, I had a great big thingee in my throat removed, and they took out this and that in there. What gave me great peace of mind, before I went in, was the thought that to the doctors, this was a mundane as driving a bus... they do it every day, but with real care and dedication.
All will be well, and so will you.
Much love
Lor
