Lower Bleph and facial fat transfer

Treating myself to a fresh face without the bags which have been tormenting me for EVER. I began saving up in early spring, and in summer began consulting with surgeons. Every surgeon suggested a different way to handle my eye bags, and I chose the surgeon whose suggestions, demeanor, staff, credentials, facility, photo, and reviews made me feel most comfortable. I paid the deposit, and booked surgery for November 27. I am so excited I can hardly believe in 8 weeks, I will be getting over most of the swelling.

I'm nervous and excited. My husband is a little scared, and so am I. What if it doesn't turn out well? What if there are complications? What if I become depressed during recovery as is so common? What if I can't sleep on my back? What if people find out that I had "work done" and judge me as vain? What if there's a catastrophe which interrupts my convalescence? Ok, maybe that's silly.
I'm sure it's natural to worry that your face or life will be adversely affected by elective plastic surgery. 
On the other hand, every time I look in the mirror, I think to myself that soon I'll be happy with my looks in way that I haven't been before. Our culture expects us to look incredible, and not to age, but also to not try too hard to achieve that. 
I am 42 years old, and lead a very healthy lifestyle. I work out between 3 and 8 hours a week (usually around 5 hours), and have for around 15 years. I don't smoke, and quit drinking 15 months ago. I regularly sleep for between 7-8 hours a night. I use tretinoin, and wear sunblock. I eat a very healthy diet. My BMI is 18.5 and has been for over a decade, so it's no surprise that I have little volume on my face.  
I have been practicing sleeping on my back the whole night, and so far, a travel neck pillow really seems to help the most, of all the variations I've tried. 
I have two weeks off of work for convalescence, and I hope that upon my return, no one will wonder if I had anything done, only noticing that I look "healthy" and "rested".

Tonight I read a bunch of my surgeon's advice to remind me that I choose a great doctor, and that this is going to be awesome. He answers plenty of questions on this site with clarity, compassion, and that deep understanding that comes from a great education plus lots of experience, which has really helped me feel good about my choice to go with him.
