My tummy tuck is tomorrow, is it normal to have so much anxiety and fear?

I have had a breast reduction and I did great with the anethesia but for some reason I'm scared, now like my anxiety level is high!!! I am 26 no significant medical history, one child birth, I am an APRN, so I know a lot of medical Information, it's just now I'm nervous like I will not wake up. Is this a normal feeling, with my breast surgery I felt like this but not as much. I've researched my plastic surgeon she is board certified and I love her, I just want to shake this nervousness
