You can consider breast implants, push up bras but to be honest the best thing you could do is to accept yourself for who you are.
You are within the body, allow that to increase and shine through with acceptance for yourself. You can't be truly at peace with yourself without it.
God gave you a beautiful body and I bet if you stood before the mirror you can see that, if can see past your own blindness with this issue.
It's not about how big they are, they are only an accessory item to the body but more importantly god given for motherhood.
Seriously, implants 'could' not all...
get problems and they aren't filling you with acceptance, you've just found a way around doing it by implants, that isn't accepting yourself for who you are.
Be thankful too, you have a wonderful life ahead of you-a healthy body (I hope) and lots to be thankful for. Don't worry about the surface when you can shine through and thrive with what you've got.
I pray you can accept yourself for who you are-a beautiful young lady with your whole life ahead of you-don't let this issue take that away by making you depressed.
God Bless you xxxx
