I have a serious problem with stuffing my bra...?

So I moved from a different state just this year away from everyone i knew and last summer i dint at all stuff my bra. Just this year i started to have a serious issue with it. And now people are starting to talk....questions like why i dont change with everyone in the dressing room and when they look down my shirt they can see stuff.. i can't swim, change in front of people. can't let a guy feel me up, and its horrid. i'm now known for my big boobs and i think im pulling off a way bigger size than i actually am. i thought i was pretty good at hiding it but apparently not becuase people are getting curious. iv'e herd it all but im already thin as heck i can't say i loose weight...i don't know of anything that actually WILL make my boobs bigger that you do not have to pay for...no one knows and now i really regret it becuase i cant wear a bathing suit...i know there is the padded bras but ive also been wearing a bigger bra so the outline size would be way smaller...ive already tried decreasing a little but now i can't wear the shirts i used to when i stuffed more cause the size difference.....i KNOW its the stupidest thing to do and now i iwsh i could go back but i cant. it's one of my biggest flaws/ insecurity. Please come up with good advice:/ i really need it:( i'm tired of it but i cannot just stop i just need a temporary boost until they actually grow..by the way im a sophmore in high school nw so yes this is really embarassing....and eyes are on me and my boobs constantly so idk what to do...please don't make fun since i already can see its bad... just help!!:/ thank you<3
