Your breasts can be corrected only with surgery. You can consult some plastic surgeon about this. I'm not an expert on the English medical system, but in my country plastic surgeries are paid for by Health insurance only if they are medically indicated. Examples of medically necessary procedures include the reconstructive plastic surgeries that are necessary after some injury or disease (usually tumors). Aesthetic plastic surgeries (enlarging or lifting the breasts) are usually not paid by the health insurance because they are usually not medically indicated but only for asked by the patents.
