Firstly you are awesome now... Next is the fact that an extra 'rack' means more likely back pain from the new additions etc.
Personally I think your great now, plus; and i apologise but a boob job will not help you with whatever might be a real issue in your life now or in the past...
Whatever the cause of your feelings will resurface after the expense and trauma of your plans, so what then ?
Will you share your plan B and plan C with us as well, good luck with your plans...
Best wishes !
