Sheyla Hershey has re-inflated her boobs with new implants following a life-threatening infection in 2010 which saw her assets turn into sagging skin.
She was so depressed that she tried to overdose and says she couldn't go on living when they shrank.
Brazilian-born Sheyla said she thought she might not be able to go on living without her massive breasts.
She said: "I almost feel whole again. Not having my breasts was killing me, I didn't know if I could make it.
"My breasts had become part of me and I was deformed without them. I felt like I had lost a leg."
"I overdosed earlier this year after accidentally taking too many painkillers, but I had become so sad that I couldn't bear to leave the house.
"I just wanted to go to sleep and wake up and have my breasts again."
Ignoring the wishes of doctors, psychiatrists and her husband Derek, Sheyla organised a tour of cosmetic surgery hotspots in Latin America in September.
She revealed: "My husband knew that I was going to Cancun in Mexico to get my breasts re-constructed.
"He didn't know that I was going to have them re-inflated with saline and that I planned to return to my previous size of 38 MMM and have the largest breasts in the world.
"I had 2,500cc of saline liquid re-implanted back into my re-constructed breasts in late September.
"And then I flew back to Vitoria, Brazil, my home town to have gradual increases added to my new boobs.
"I increased slowly over a two-month period and now my breasts are back at 4,300cc of liquid and are 38KKK.
"In the New Year I will have them back to 5,500cc or 38MMM when I go for surgery."
Leaving her husband, Derek, 29, back home in Houston, Texas, Sheyla deliberately lied to him about her surgery.
Sheyla said: "He was asking me for pictures to see how the surgery had gone, but I kept on telling him to wait till I returned home.
"When he saw me he was shocked and hurt that I had lied to him. I told him that it is my body and I can do what I want to it.
"But he didn't talk to me for a week and he threatened me with divorce.
"I told him if he wants one he should go get one, but he didn't and now he has accepted my breasts are almost back being the way they were. If I am happy, then he is happy."
