38 Years Old, 2 Children - Not Happy with my Deflated Girls, Getting 325cc or 375cc - New Zealand, NZ

So I have been on this site since the start of the year, reading and gathering so much information and insight. It has been very easy to find a whole swag of 'wish' boobs and some 'do not want' but I am still undecided on final size.
I am 5'3, 60kg and current bra size is 34b/c but not full.
My surgeon who I first met back in February has suggested 375cc to achieve the look I want/like. I have played with rice sizers ranging in size from 300cc to 425cc but am thinking the lower end of the scale is more suited to me. I am very active with running and gym workouts - I put off getting the surgery due to entering a half marathon which I completed a couple of weeks ago, so this is a big factor in my decision making.
At my second consult I tried the 325cc which I liked on me, unfortunately he didn't have the 375cc there. I did try the 400cc which we both thought made me look 'done' - only a few people know I am having this done so that is not the look I am going for.
I am booked for 7.30am on 25th May, I really want to be excited but my nerves and anxiety is taking over!!!
I will post before pic shortly - my phone is having issues.

Hope everyone else's journeys are going well.

What a great experience. I can't say enough about how well I was treated today by all the staff involved. I ended up getting 375cc and am feeling pleased with my decision at this stage. My surgeon mentioned 400cc - I almost laughed at him!! Haven't really got much pain except when I sneezed, that was a little sore :) Keeping on top of my meds today but will look at weaning off the pain ones tomorrow.
Surprisingly I haven't got the girls out to have a good look so no pic's just yet. Will sort some tomorrow.
Happy healing ladies! X
