I am 19 with severe sagging breasts, is this normal? What are my options? (Photos)

I am 5”4 and 145 pounds. i have had sagging breasts since i hit puberty at 9. i also lost some weight around the age of 14, which im guessing contributes, but my breasts have been saggy since i was about 11, but that’s not something you really think about at that age. i hide it from all of my friends, but i am genuinely extremely insecure. i am unable to wear bathing suits, most normal bras cause extreme gapping, and even tube tops have to be paired with a bra. i have a lot of friends and we have all seen each other naked at some point, and even my friends with bigger breasts don’t sag this much. i am also decently active, i work out my chest muscles pretty often. i’m not sure if a breast augmentation is even worth it, because all of the skin that is there is probably what makes my boobs have any volume, and i don’t like the risks associated with implants (or the aesthetic of fake boobs). i have thought about surgeries since i was at least 14. i absolutely hate my breasts, and the only thing i have not done is ask a professional.
