Weight loss and boobs!

Im naturally curvy and petite

Ive always been in shape but recently due to insulin resistance my diet changed and i lost 13 pounds

I finally have a flat stomach! But with that my butt (which was really nice) became flatter

Also lost weight on my boobs and all my bras are loose now, i usually wore a B cup, i was fine with it but now i am just so insecure with my body, i miss my curves!

I know that you can grow your butt with working out, but theres no escaping from a flat chest! I see lots of fitness accounts where the girl has fake boobs. It seems like its the only way to have good curves and still have a flat stomach

Even when my bf tells me my boobs are perfect rn, i feel they are so small for him (hes a boob guy)

Im just venting and would like to know if someone else feels discouraged by this, its hard for me to decide between being skinny with a flat stomach or gain weight to be more curvy.
