Hi, Thanks for using HCM
Firstly i would like to advice you to just relax and stop worrying
If i would recommend you few things for growing your breast
1. Gain some weight. Breasts are comprised primarily of fatty connective tissue
. If you are very thin, then putting on a few extra pounds (i.e. fat) might help fill out your breasts.
2. Build your pectoral muscles. Building the muscles underneath your breasts can help improve size, firmness, and perkiness.
3. Be patient. Most women's breasts don't stop growing until they are in their mid-twenties. You are still in your teens, it's likely that your body hasn't finished fully developing, so give yourself time before trying to alter your breasts, natural or otherwise.
