Why is one of my boobs smaller than the other boob?

Anonymous
I'm so insecure about it. And I'm 14, turning 15 later this year. According to google I'm done with puberty, and if my breasts are uneven at this age they will be uneven permanently.
Is there any way I can make my boobs the same size?
I got my period at age 12, almost 13.
Please I just want to look proportional.
Not to mention I'm also insecure about my height. I won't grow anymore and I feel too short. I am 160 cm (5'3) and all the girls my age are 5'5 or taller. If I'm done growing I will be 5'3 for the rest of my life. Not to mention I'll shrink when I'm old.
