Hi there,
I think this is very normal, even if we have had surgery in the past, we still feel nervous/panicky, we will worry about how we come out of surgery,the healing, long term progress, and just the whole thing.
I have had surgeries in the past, and 3 surgeries this year, one for my ear, with no anesthesia, the 2nd growth removal on back, just novacaine, but the 3rd was major internal/nasal surgery, where I was knocked out for 2-3 hours. This was the one that worried me, between being knocked out, surgery and then this long healing process, 6 months to one yr for total.
I'm sure you'll do fine, just keep convincing yourself that, and if you have been prescribed anti-anxiety meds. use them, as prescribed, of course.
You'll be in my thoughts.
Lots of luck,
DE
