Getting Ready for Oct 16! 350cc?

I'm 28, 5'7 and around 115 lbs.  I'm a 32a- even smaller when I'm off birth control!  I'm thinking about getting 350cc or maybe even 375 cc.  Any of you girls have similar stats?  I'm wanting a full C cup, and I'm hoping this will get me there.  It's so hard to pick the size!!On another note, I went by WalMart today and got a few items that seem to be good for post-op.  I'm too excited to wait!:-BioSil (heals scarring/helps get rid of scars)-Cocoa Butter Stretch Mark Cream (I assume this might help my new boobies stretch out)-Scar Strips (the tape that you can put on the incisions)-Emergen-C (vitamins and lots of Vitamin C which should help with recovery)-Genie Zip Front Sports Bra (I only saw 2 in the store, both were size M.  I don't know if I'll need a medium or not yet, but decided to get it!  I almost got black but then saw someone had taken it out of the package and had deoderant marks all over it.  I went for the white one that was left.  Hope medium will be enough support!)-Wedge Pillow (which I didn't find there! I'll have to look somewhere else!)I am so excited and nervous about the surgery.  Truly, I'm mostly worried about all the problems that could happen later from it.  However, as soon as I planned to do this I really really felt sure that this is what I wanted.  What do you girls do when you feel worried/paranoid?  Also, do you feel weird about what people will think?  I'm going to try and keep it to myself for the most part, but I had to tell my boyfriend for example.  I wonder what he thinks!
