FL GIRL 19 Yrs Old, 105lbs, 5'2, 265cc silicone HP gummy bear unders

Hey ladies!
Quick overview and wishes for my pre and post BA:
Growing up, and even now, I have always had small breasts. They have made me miss out on SO much already. Beach trips, cute clothes, and my self esteem have all taken a hit due to my lack of confidence in my body. I'm pretty petite, and although I'm young and a sophomore in college, I work at an office that requires me to be dressed professionally. It is already so hard to find slacks that fit my short legs, finding dresses that fill out my the boobs and under arms is beyond frustrating. I end up feeling so insecure leaving stores. That is just one of the reasons I have decided to act on getting this surgery. Another is just being naked in general. When being intimate with my boyfriend of 3 years or even just changing in front of him, I find myself hiding my breasts. I hate when he looks at them or even tries to touch them because I feel hideous. He really doesn't want me to get the surgery because he thinks I'm beautiful just the way I am, but at the same time if it helps me feel better about myself then he's 100% supportive which is amazing. My pre-op is June 7th, and my surgery is that following Wednesday, June 14th @ 11am.
I. AM. TERRIFIED.
My PS used the 3D imaging to show my what my results would somewhat look like. He says I can use either Saline or Silicone, but recommends saline because of my age and the likely hood of needing some type of increase or anything like that years down the road. I've never had any surgery or anesthesia before so I am fairly nervous about it. My PS is Dr. Lewis Obi, located in Jacksonville FL. He has been practicing for years and seems to be an amazing doctor. My only concern is his age because he is an older gentleman, however he has so much experience and great reviews I'm really trying not to sike myself out about it!
About my SURGERY:
Dr. Obi is doing the perriolar (if that's how you say it) incision with 365cc saline implants. He estimates I'll be a full C which is EXACTLY what I want. Still super scared that they will be too big, too small, scaring will be awful, procedure complications.... yes I'm terrified. But he is the expert and I know women who also had the same incision and say there is no scar at all, especially when they tan.
Question for you ladies who have had a BA before children: WAS IT A COMPLETE WASTE?
I'm just so ready to feel beautiful in my own skin. This will (hopefully) give me the confidence I have been dying for since I was 12 years old! Still debating on uploading my pre-op pics, but hey why not!
Pray for me!!!

Attempted to update some before pics but it won't let me update via iPhone, looks like I'll have to wait until I'm more mobile to upload from my PC!

So I had my procedure at 11am, June 14th. Originally I chose 300cc saline implants with a nipple incision with Dr. Obi. After seeing all the reviews on the gummy bear implant, I knew I HAD to have them. Obi approved and it only brought the price from 4900 to 6k which was totally worth it. Still did periolar incision, however the largest he could fit in my frame was a 265cc. He said this should give me the large c I have been praying for!! So far, I've been in a LOT of pain. And he's wrapped me with a wrap that sticks to me so I can't get a peak at the girls!! He did show my boyfriend a pic of me from the OR and my boyfriend said they look great. I'm just terrified of the boob greed but I know that I would rather have natural looking than something far too big for my frame. I go on for my first post op visit tomorrow and hopefully I get the drains removed! Thank you realself! You have been a HUGE help in this process.
