Would a breast lift help my back and posture? (photos)

I have had 4 pregnancy and 3 births.. prior to kids I was a 36d. With my pregnancy my boobs went up to 38h (when full with milk the cup size of the bra was too small).. now I am am a 36dd(uneven) and I find my self leaning forward a lot to feel balanced.. and my upper back and neck are always in pain.. also my nipples are always sensitive
