I'm at the end of my rope help please I'm desperate

Jas❤️❤️
I don't want to appear like the typical person complanning about my body I'm only 19 but I'll just put some sizes out there then explain
U.K.
Boobs-32J
Waist-12 
Height- 5 foot 2
Weight- 150 pounds
For the people in the us 
My waist would be an 8
 Okay as you can tell these are ridiculous proportions for my boobs they're huge and I can't decide if I want a reduction 
I get back pain all the time and side pain I've had physiotherapy for it 
Losing weight makes no difference except shrink my waist which puts more stress on my spine 
My breasts push against my lungs so at night when I'm trying to sleep I can't because I can't breathe properly and get enough air in my lungs 
Sometimes I cry myself to sleep at night because i feel like a circus freak 
Guys will comment out loud if I'm just walking past them
And a couple dozen more will stare
I've been shouted at across streets since I was 14 because they're abnormally large for my size 
But I went to my gp and I wear clothes that make them appear smaller so all he said was they don't look big wait if they get bigger and your too young 
But my self esteem issues mean that the scars are scary and I don't think I'll be found attractive anymore 
I need advice please
