Sagging skin/cheeks after filler - if I get filler, they will just get worse?

A year ago I had fillers in my upper cheekbones which I did not need, and they gave me too much which caused the lower half of the face to deflate. I since had to have filler in the lower half of my face to even out, but I feel they gave too much and now they've worn out, the bottom of my face sags awfully. This was never a problem. I'm mid 30s and I have sagging cheeks now! I fear if I get filler, they will just get worse and worse. What is the best solution? Will they ever go back to normal?
