>>How can I replace what they took away?<<
You can't..... done is done. You can consider more surgery in an attempt to REPLICATE your appearance prior to surgery, but you cannot turn the clock back on living tissue altered by surgical manipulation.
>> Instead I am searching for a way to put back what was stolen. <<
How do you think you might accomplish this? By means of further surgery?
>>I had second thoughts about the forehead lift prior to surgery as well, but the doctor convinced me to go ahead with it.<<
Oh, I know this feeling well

On the way to the hospital on the morning I was to have the rhinoplasty that ruined my 8 wk old healing facelift, I felt like turning back and canceling the whole thing. If I had listened to my own intuition I would not be living every day in Hell.
Melanie, take it from one who knows.. realize how lucky you have been and QUIT WHILE YOU ARE AHEAD. I wish I had.
