I want bigger breasts? I'm so disgusting? - 1

I'm 14 years old and I have major self esteem issues.

To sum it up:
I hate the way I look, I wish I were at least a year older than I actually am (I turn 15 in July, ugh.), I'm just overall disgusting and I'm sitting here bawling because of the stress that I put myself through every single day even over other things. I'm so hard on myself it isn't even funny. I fend for others and don't usually get the same in return. I'm so angry. I want to be prettier. I know that you'll say "You're only 14! Don't rush to grow up." Well, yeah, sure I'll feel horrid when I'm older and wishing I were younger but this is now. This is now. I want bigger breasts now, I want to be prettier now, I want to go to that One Direction concert but no! I guess not. My friend whom is 15 has bigger breasts, an iPhone, gets to go to the concert, she's far more pretty than me (She's Italian). I guess I sound pretty immature and ungrateful but I don't know what to do anymore. Just please, help.
I also started my period about two years ago and began puberty at a very early age. I want to know whether my breasts will grow larger and if so- how soon? That is one of the main reasons I have such low self-esteem.
I forgot to mention, well I thought I did, that I have a 34B bra size and my mother is a D or something I believe. Most women in my family have very, very large breasts so.

Wait for yourself to grow, seriously I'm 14 a 34E and I'm still going, I'm not even fat cause it's by genetics, but to honest you're just comparing yourself to others, instead of looking at them help yourself to become more beautiful to make you appear and feel beautiful, I was in your same shoes until I started trying make-up and now I feel more confident about myself when I now know I made an effort to look this good for me. Don't envy.
Because everything will come together eventually, but be happy with what you got, express what you have and let it take its time.

My parents taught me at a young age to not compare myself to anyone else because you can't always have what everyone else has. I think if you stop comparing your life to others that have more than you do, you will be happier. You are still young and you are still growing so let your body do its job and maybe the results will be in your favor.
