No non-surgical breast lift

A photograph of your breasts would allow a plastic surgeon to definitively answer this question.

From what you are describing, you undoubtedly have breast ptosis (sagging or droopiness). A surgical breast lift or mastopexy is the only way to reliably lift your breasts and restore a more youthful, aesthetically pleasing appearance. Done correctly, using the breast tissue itself to reshape and lift the breasts, a mastopexy can produce attractive and lasting results. 

Beware of those who promise equivalent or lasting results with a "non-surgical" breast lift.
