What exactly are you nervous about hun? Is it the op? the recovery? the result? or all of it haha!
I was a shivering wreck when i was going to theatre but there really isnt anything to be worried about. The doctors and nurses know what they are doing and while your under anaesthetic you cant control anything anyway so just let it go. As for afterwards ul be more uncomfortable than in pain but ul be given ur meds so as long as u take them and dont try to do too much all at once ul heal well.
Just keep focussing on ur lovely new boobs ur going to have and dont think about HOW theyre going to get there if that makes sense.
Honestly ul wonder what on earth u were stressed for afterwards! xxx
