Why do i feel so trapped?

I'm 13 years old (I know I'm a bit young to worry about it), but I'm still flat chested. And when I say it, I MEAN it. I do LITERALLY look like a 6 year old girl. When someone meets me they say 'Oh, how old are you? 9?' I've had that said to me before. I...

feel like such a complete and utter freak. When I was 10 and I learnt about puberty I was like 'Oh, I'll be normal like everyone else. When I'm 12 I'll start getting boobs. Theres nothing in the world to worry about!'
I'm the only person I know who is 13 and still flat. I just don't want to turn 15 and see that I'm still flat, because my mother will take me to the doctor and it will leak out at school, and then everyone will say 'Isn't she that girl who had to go to the doctor because she's got no tits?'
I was crying so hard last night, and I banged my head against the wall and I wanted to die. Whats wrong with me? Why won't I just GROW?

omg lol im a 15 year old dude I feel creepy 4 answering this lmbo but im having fun answering lots of ?s dont worry about it everyone grows at different times itll b alright

Nothing to worry about, although it seems dreadful right now... are you very athletic? Sometimes athletic girls take longer to reach puberty. It's probably just around the corner

The good part is you'll probably always look younger. Imagine when you're 50 and everyone thinks you're 35...

No, I'm not athletic, I hate sports! I've started puberty I think, but my chest is still flat annoyingly!

Don't feel bad about it. I know exactly how you feel. I didnt really start developing boobs until I was about 16 or 17 and I remember being made fun of because of it. I'm now 21 and I'm still an A cup, and you know what? I'm perfectly fine with that. Huge boobs can cause back problems and get in the way. Everyone develops at a different rate so dont worry about it.
