like others here are pointing out, being very very nervous is just natural in this situation. spine integrity, especially in neck zone, is very serious thing (me-statement: i have had mine compromized as long as i remember, after an incident at the age of 6, that damaged my neck vertebrae. i have a very up-close and personal idea what even minor in the start spine damage can do to a body). ofc modern surgery is well, getting more efficient by the year, and things that had not been possible, become mundane. feeling nervous is very exhausting, but blaming urself for that is really well, just wrong (me-statement: i allways am nervous when i need some surgery done, and i mean, that it happens to me enough to use the word always. i know the feeling. i relate). let it wash over u. have some comfort treats of ur preference. let ur family/friends take care of u, its a need u have at this time. fare well, hope to hear from u how that new disc is absolutely cool for u)
