I Have Tuberous Breast and Only Got a Breast Augmentation, I'm So Unhappy and Depressed. What else Should I Have Had Done?

Relax.  There are two problems, and you can solve them both, your breasts, and your reaction to them.  

The breasts may need further surgery down the line, but they're yours to show or hide as needed.  Be proud of your body, you have the only one ever made like it.  Always be yourself... those who mind don't matter, and those who matter don't mind.  You learned a very important lesson:  Do your research, know who is who, and price should be the least important criteria upon which you select a surgeon.

Far more important than the technique is the skill and experience of your plastic surgeon. Choose your surgeon rather than the technique and let them explain why one technique may be better than another.  See the below link on some suggestions on finding the most qualified Plastic Surgeon for a Breast Augmentation.  Always insist on a board certified plastic surgeon.

I am sorry you are going through this, but there is an answer to your problems.  If, in fact, you had tuberous breasts pre-operatively, then this is not an unusual situation.  The problem with tuberous breasts is that they have a very narrow base to their breasts which makes them look like a tuber (potato).  If the implant is placed below the inframammary fold, then you will always get a double bubble.  If the implant was based at the inframammary fold, then your nipple would come out too low on the breast mound.  Tuberous breasts, at times, turn downward, and unless a lift is done at the same time, they get what is known as the "Snoopy Nose Deformity". 

Depending on the position of the implant, you may need what is known as a capsulopexy where the pocket for the implant is lifted.  When a tuberous breast is on top of the muscle and the implant below, there is no ability for this tight constricted base to splay out over the implant, giving a more natural appearance.  If you plastic surgeon told you that a tuberous breast can be corrected with just an implant, then I highly recommend you seek a second opinion from a Board Certified plastic surgeon in your town, experienced in the circumareolar or Benelli mastopexy as well as the dual plane mastopexy.
