Yeah...those videos can be a bit graphic for us non-medical types! So what scares you about the surgery? You'll be blissfully asleep, so you aren't going to know or feel anything. It's like that time just doesn't exist for you!
But, even so....some people are afraid of pain, of waking up during surgery, of not waking up afterwards, of the lack of control (putting everything in someone else's hands), of it not working, of the recovery process afterwards....any of these sound familar to you??? Or are there other things I've not mentioned? Once you get it out and we can talk about it, you should feel a little more at ease.
