@sarge15926 There’s no answer for you, Sarge…it’s totally normal to be anxious, nervous and fearful from ‘all of it’.
Just remind yourself of why you have to do this (family history) and how many others before - and after you - have experienced the same doubts and fears.
We all came out the other side and lived to talk about it. If you trust your surgeon and believe in his/her skills just LET GO and let them do what they are expertly trained for…Best,
