I now feel weird about my boobs

Hi, I’m sorry if this rant will make no sanse to someone but I now feel weird and ashamed about my boobs.

I’m a small girl that until 6 moths ago had small boobs, I experienced now (19F) a sudden growth and this make me feel weird about them.

I’ve always went braless, I know can’t do it anymore and I even feel that with a bra everyone is looking at them, when before no one was.

I’ve tried to talk about this with my friends but they told me I should be thankful about them and not weird. At home it’s just me and my dad so I don’t feel like he can understand this.

If anyone has experience the same thing please let me know for any advice.
