My face lift is in 6 days, feeling nervous!!

Hi all,I've been reading and looking at all your pictures here.  Thank you so much for sharing! I'm getting nervous! Please help me feel secure about this whole thing. I'm 51, very fit and have been noticing my neck looks saggy/wrinkled in pictures.  I'm so picky and want a youthful look.  My jowels are beginning to sag also.  I booked my facial rejuvenation surgery for Nov. 7th at 9 am with Dr. Mitchel Blum.  He has loads of experience, excellent reviews and I like him.  But I can't help but feel nervous about changing my face! Should I worry? Are there negative outcomes? I hope to hear from those of you who have gone through this experience! Thank you!
