So Excited to Feel Pain Free! - Australia, AU

I am 30 years old and live in Australia and All booked in for a Breast Reduction in 19 days! So scared and nervous and excited all at the same time! I am currently a 16H, which in other sizes is 38H US, 38i UK, 85J EU OMG Tig ol Bitties lol
I have already had my consultation wi5h the surgeon who was soo loveley and very informative, all been paid for around $7500 surgeon fee, $2000 anesthetic fee and $500 for misc cost like surgical bras, silicone scar plasters, and healing supplements to help reduce scarring and boost healing which are ArnicaEze, Zinc, Vitamin C & Vitamin B5. I have top private health cover so I wont be paying for the private hospital and will be getting a portion of the surgery costs covered.

Just wondering if any of you ladies have this same hangup with your big breasts, where your arms don't sit by your sides properly and are always resting on side boob! Having my arms swinging freely is one of the the luxuries I'm looking forward to after this surgery! ?
PS: Oh and also having bra straps that don't dig in xx

For the people who think I should not go through with it here is my reason!
I have no problem with the way my breasts look. My decision to get this done is not based on vanity, it is because of the years of pain I've endured! I want to be able to move freely and chase after my little one and be able to take up running for better health for my future. I have enjoyed the attention I have received from having a big rack through my 20's and that's why I have left it until I turned 30. They have served there purpose as I breast fed my lil one for 15 months so it's now time for them to go and for my back, neck & shoulders to heal. So I may look perfect to you but I'm not healthy and that is more important than what I look like. My husband is very supportive and excited to see me more active once I get this done.
