You're doing such amazing progress sweetie. <3 Both on boobs and everything else. I'm super happy to see you bounce back from the bottom of the wave recently... And why shouldn't you, you're developing into such busty cutie, that alone should cheer you up 24/7.
And speaking of fast breast growth, I'm sure you will be breaking records. I've had periods of fats growth, but not as phenomenal what you have going right now.

Let me predict that you will completely fill up that FF cup bra before month and half have passed.
